© 2014 IEEE.This paper describes a spreadsheet platform for learning signal processing called SignalSheets. SignalSheets consists of sections, each represents a signal transformation from input to output. We use SignalSheets to explain a design process of a finite impulse response (FIR) low pass filter. It starts with a design assignment describing LPF specifications. We assume a FIR linear constant coefficient diference equation (LCCDE) filters as implementation form. We then use windows technique to obtain the LCCDE coefficients. Coefficients are a result of multiplying ideal coefficients with a window function. The paper shows how ordinary spreadsheets such as Gnumeric can simulate standard as well as advanced signal processing concepts.
