Square WaveThe square wave is a periodic waveform consisting of instantaneous transitions between two levels which can be denoted . The square wave is sometimes also called the Rademacher Function. Let the square wave have period . The squarewave function is Odd, so the Fourier Series has and
The Fourier Series for the square wave is therefore
