Communication Techniques: A Hardware Approach Communication techniques needs to be understood in hardware circuits. We will be using Arduino Serial plotter to plot graphs and waveforms. The below PDF reader contains the necessary details,procedures and understandings of circuit realisation of communication methods.Hope you'll like to see.

Square wave generation using TTL TITLE- GENERATION OF SQUARE WAVE USING TTL LOGIC AND COMPARISON WITH NORMAL SQUARE WAVE GENERATED USING A FUNCTION GENERATOR.
Here we’ll be showing two methods to generate square wave using TTL Logic. One using a Schmidt Trigger Inverter and another using a Ring Oscillator. Below is the detailed description


Block Diagram Reduction

This project deals with block diagram reduction. Practical and simulation done using OPAMPS. Circuit diagram and corresponding block diagram redution shown below.Also simulations and practicals done below. The block diagram deals with summing and multiplication of blocks and it's equivalent reduced figure. We did a theoritical vs practical observation, which was successful, as you can see in the pics.OPAMPS used are LM324 and LM358. Power supply given +-12v. Input signal 1khz,100mv. We successfully got around 5v which matched with our theoritical calculation. Required knowledge is only about opamp gain calculations and block diagram reduction foumulae.

Problems and Simulations
This is a small document which demonstrates theoritical problems and their simulation on Multisim. Multisim is an online tool for simulation. A free version can be used online with limited features. You can do the simulation of these problems on any other SPICE simulation software you may like (example Circuit Lab, LTSpice,etc).
