This repository contains my project on Printed Circuit Board deisgn The project involves designing an Amplitude Modulator and Demodulator on a single PCB, demonstrating the principles of amplitude ...

AM Modulation: Generating an AM signal using a switching modulator circuit and evaluating it in both the time and frequency domain. AM Demodulation: Recovering the original message signal using an ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Abstract: This paper presents an economical function generator and delta modulator circuits, which consist of hysteresis and wide range tunable voltage to current converter (VIC) for synthesizing the ...
