What is symmetrical square wave?

A Square Wave Waveform is symmetrical in shape and has a positive pulse width equal to its negative pulse width resulting in a 50% duty cycle . Square wave waveforms are used in digital systems to represent a logic level “1”, high amplitude and logic level “0”, low amplitude.

A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum .

Answer: The output voltage is in the form of a spikes corresponding to the rising and falling edges of the square wave and the output voltage is zero when the input is constant.
