Basic Idea

Analog modulator for DRSSTC with max PW limiting. This is just the basic idea, concept seems "sound" hehe. Simulation is with two sinwave inputs one at 500Hz the other at 450Hz mixed.

 

Keep in mind this modulator is not for playing complex music, it is mainly so that instruments with an analog output (such as guitars) can be played threw a DRSSTC.

 

Things to be added:

1. active Input filter

2. preamplifier

3. max duty cycle limiting

4. dynamic duty cycle control

Done
