Thus, by differentiating the RC signal you can reconstruct a signal that more closely resembles the original square wave. The differentiator output is followed by a comparator to create a sharp square ...

The most basic circuit in any synthesizer is the oscillator. A square wave oscillator constantly alternates between two voltages, in this case +5V and 0V.

In this minimalistic square wave generator circuit, the RC network is composed of a 4.7KΩ resistor and a 100nF capacitor. So, we obtain a frequency of approximately 1.5kHz. Since the output square ...
