For power, the circuit uses a 1.0 Vpp, 1kHz sine wave layered on top of a 10 V DC voltage source. For the input signal, a 0.3 Vpp, 300 Hz sine wave is applied. Advertisement. Figure 1 Mixing a sine ...

To generate our 1Khz square wave, an 8-bit counter (Counter8_1), fed by the output of the 16-bit counter, was set up to divide by 200. The compare value was chosen to provide a squarewave output.
