WebJun 6, 2024 · I was thinking along those lines, but if it’s necessary to determine the signal is actually a ‘square’ wave, the digital input hysteresis will only give a rough indication, and no assessment of the rise/fall times. It’d be great to simplify it more, but the biggest challenge in my thought is the sampling rate of the waveform’s shape. WebMay 22, 2024 · Deriving the Coefficients. Consider a square wave f ( x) of length 1. Over the range [0,1), this can be written as. x ( t) = { 1 t ≤ 1 2 − 1 t > 1 2. Fourier series … WebThus, the rise time is dictated by this last term, which in turn dictates highest frequency. An ideal square wave will have a zero rise time – but that would take infinite bandwidth to reproduce with this method. This square wave’s discontinuity is the heart of the problem, and is the reason for the preshoot and overshoot seen above. quarantine approved hotels manila
