Abstract

Presents an Excel spreadsheet that allows the user to change the parameters of a simulated digital filter and see the effect it has on a noisy signal. The spreadsheet consists of two sheets that demonstrate the efficacy of a Fourier Transform frequency-domain square-wave apodization filter on a signal containing environmental or a white noise source.
