Description: Computes the discrete fourier transform of a data set and creates a discrete frequency index vector. Generates a figure and plots data spectrum.Generates a low pas filter and multiplies with data spectrum. Generates a figure
and plots filtered data spectrum.Computes the filtered discrete time data set. Generates a figure and plots the filtered discrete time data set.Generates a high pass filter and multiplies the filter and data spectrum. Generate a figure
and plots the filtered data. Computes the filtered discrete time data set. Generates a figure and plots the filtered discrete time data set. Creates a discrete frequency index vector and simulates a data set. Generates a figure and plots the simulated data set. Create a bandpass filter by multiplying a low pass filter with a cosine function in the discrete time domain. Plots original and filtered data spectrum.
