Hey fellows, Welcome to another lecture in the signal and systems series in which we are moving towards another transform. Till now, we have studied the Laplace and z transform and we, therefore, know the basic purpose of transforms, that is, to convert the signal from one domain to another. In today's lecture, we will be discussing the Fourier Transform, and you will enjoy its information because now we have a clearer idea of what we are doing and what the purpose of this transformation of a signal is. Here are the key points that we are going to consider:
What is the Fourier transform?
What is the journey Fourier transforms from start to end?
How do you define the types of Fourier transform?
Why is the Discrete Fourier transform important?
Why is the fast Fourier transforms named so ...
Chemical engineering combines experimental and natural sciences like physics and chemistry and other sciences like microbiology, biochemistry, biology, together with mathematics economics all of these to develop, transform and manage the industrial processes that run raw materials into valuable products. Chemical engineers are in high demand increasingly daily as the world’s technology advances. In this post we are going to look at the basic requirements for a chemical engineering career.
1. Solid Educational Background
The requirements for a chemical engineering degree in tertiary institutions like American International College
is normally a very strong educational background in mathematics and chemistry whereas knowledge in the other sciences will be an added advantage. At the tim ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 2N3906. It is most common Positive Negative Positive (PNP) Bipolar Junction Transistor (BJT) available in the market now a days.
2N 3906 is specially designed for low power amplification purposes as well as for switching purposes. 2N 3906 is designed for low current, power and for medium voltages. It is capable of operating at moderately high speeds. The range of its collector current is form 10uA to 100mA. Further detail about 2N-3906 will be given later in this tutorial.
Note:
You should download 2n3906 Datasheet by clicking below button:

Hello friends, I hope you all are doing great. Today, we are going to start Section-III of our Raspberry Pi 4 Programming Course. In this section, we will interface different Embedded Sensors with Raspberry Pi 4. Today's our first lecture in Section-III, so I am going to interface a simple LDR sensor with RPi4.
So, let's get started:
Components Required:
The following items are required to finish this Raspberry Pi
photoresistor module guide. You don't need a breadboard to accomplish
this, but having one would be helpful.Raspberry pi 4BreadboardPhotoresistor LDRJumper wires1uF Capacitor
What is a photoresist?
It is a common practice to employ photoresistors to determine the presence or absence of visible light or to quantify the amount of ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a very quick and basic tutorial in which I will show you How to use Arduino Serial Flush. I hope you guys are going to like it. We have seen How to use Arduino Serial Write? In that tutorial, we have sent some data over the Serial Port so you must recall that tutorial because we are going to use the same example today. Moreover, it's also good if you have a look at How to use Arduino Serial Monitor because that's also related.
Moreover, I hope that's going to be my last lecture on Arduino Serial Port because I have covered it in full detail. Although I am going to summarize all the Arduino Serial Post Commands in a single Post. You should also have a l ...
Hello everyone, I hope you all are doing great. In today's tutorial, I am going to share the detailed fIn the previous post, we have seen Introduction to PLC, which was quite simple and has the basic introduction to PLC. To day we are gonna have a look at Getting Started With Ladder Logic For PLC. Ladder Logic, also named as Ladder Logic Programming, is the programming language for PLCs. Its normally considered as the most difficult language among the engineers because of its complex structure, but if you ask me then I will say its the most interesting programming language.
Ladder Logic is different from the usual programming language of Microcontrollers like Arduino, PIC Microcontroller etc. Microcontrollers programming usually compiled from top ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge with all of you guys about DC Current Sensor ACS712 Arduino Interfacing. First of all, I would like to tell you about importance of current sensing/measuring. Sensing the amount of current passing through any circuit can be useful in a lot of applications. For example, in low power consuming equipment, current sensing will be helpful to understand the system's impact on its battery life. The current sensing can also be used to make the decisions regarding safety in over current protection circuits.
Simply, we can say that sensing and controlling the flow of the current through the circuits is now a fundamental requirement e.g. over curr ...
Moving complex machinery across the country is no small feat. It demands meticulous planning, organization, and utmost caution throughout each step of the process. To that end, let’s discuss eight best practices that can streamline your move and ensure your equipment arrives at its new home intact and functional.Understanding Your Equipment
When gearing up for a cross-country move of complex machinery, the importance of gaining deep insights about your equipment cannot be overlooked. Here are several points you need to consider:Identify sensitive components: Knowing which parts of your machinery are delicate or more vulnerable can help avoid potential damage during transit.Analyze dismantling options: In some instances, disassembly may simplify transportation and reduce risks.Evaluate wei ...
Hello friends, in today's post I am gonna show how to send SMS with PIC Microcontroller and SIM900. In my previous posts, we have seen how to Send SMS with Arduino and SIM900D and have also seen how to Receive SMS with Arduino and sim900D, both of them were using Arduino board. So, today I thought to post same project using PIC Microcontroller. The logics I am gonna use are exactly the sameas I did for Arduino but the only thing gonna change is the programming syntax. I am using MikroC Pro for PIC compiler for PIC Microcontroller and PIC18F452 is gonna use here. I have also posted on How to Receive SMS with AT Commands using SIM900 & PIC Microcontroller, so check it out as well if you are planning to work on PIC Microcontroller and SIM900.

Hello everyone, I hope you all are doing great. Today, I am going to share a very basic tutorial on PIC Microcontroller, which is Interfacing of Keypad with PIC Microcontroller. I have designed this simulation of Keypad with PIC Microcontroller in Proteus ISIS and the simulation along with code is given below for download. But I would suggest you to read it first and then design it on your own so that you learn most out of it.
In today's tutorial, I am not gonna discuss the details of How keypad works because I have discussed it in detail in my old tutorial Interfacing of Keypad with Arduino so if you don't have much idea about working of keypad then I would recommend you to read that tutorial first, before proceeding with today's tutorial. I hav ...
