Analysis of Signal Filtering using Lowpass and Highpass Filters, Exercises of Electrical Engineering
An analysis of signal filtering using lowpass and highpass filters. The frequency response of the filters for individual sinusoids at frequencies 50 hz, 200 hz, and 1500 hz, as well as the filter output for the combined signal. The document also includes spectrum representation of the original signal, lowpass filtered signal, and highpass filtered signal.
