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 ...

TEXT -416 -152 Left 2 ;Opamp gain depends on JFET resistance which is modulated by the modulating signal TEXT 64 -104 Left 2 ;Vsignal is the modulating 10kHz signal TEXT -408 184 Left 2 ;Modulated ...

This circuit was originally designed as a simple mains intercom for use in the home. To complete the circuit you could use the ‘Mains Remote Transmitter’. We have to admit that our tests with the ...

Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...
