Document Summary

Only defined at discrete times: analogue converted into digital using a/d converter, spectral analysis, any waveform can be mathematically decomposed in a sum of different waveforms, resolution, saturation, example. Should span voltage range to increase signal to noise ratio: aliasing, higher ratio increases resolution voltage_ range resolution = Sampling rate must be greater than twice the highest frequency contained in the analogue signal in practice, go 3 4x higher than frequency: quantization error introduced by digitizing process, determined by accuracy of digitizing process, why not sample at the highest rate possible, cost of a/d converter increases, more computer processing time, computer storage space used filters low frequency = high pass filters out low frequencies, high frequency = low pass filters out high frequencies, notch filter filters out one frequency, usually 60 hz, north american power line, real filters = hardware filters irreversible change composition of signal.
