### Simple Filter Turns Square Waves into Sine Waves

a simple filter. According to its Fourier series a 50 duty cycle square wave consists of odd order harmonic sine waves with the fundamental at the same frequency as the square wave. square wave. This is because the fundamental has an ampli tude of 4/π times that of the square wave as shown by the Fourier series.

May 06 2016  When a low pass filter acts on a square wave the output is something similar to this My question is simple. If the filter is a low pass filter it should filter all frequencies that are above some constant frequency the value will depend on the circuit and let only lower frequencies pass right . If this was true the output should be something like this
