The system he has come up with is so simple it’s borderline genius. The PWM signal in question is fed through a piezo speaker in parallel with a resistor. The output from the speaker is then ...
The main simplification was using a constant PWM signal. The result is that the ... The reason is — as I mentioned in the first post — in real life, you probably shouldn’t be doing all ...
As described in the earlier DI, switches U1b and U1c accept a 10-kHz PWM signal to generate a 0v to 11.25v “ADJ” control signal for the U2 regulator via feedback networks R1, R2, and R3. The incoming ...
