Design a MATLAB program to implement an FIR filter for enhancing signals in a specific frequency band. Assume the signal is sampled at fs =10,000 Hz, and the target frequency band is 1000 Hz to 3000 Hz.
1. Design a bandpass FIR filter using the windowing method (e.g., Hamming window).
2. Plot the frequency response of the filter.
3. Generate a test signal consisting of sinusoids at frequencies 500 Hz,2000 Hz, and 4000 Hz, and apply the filter.
4. Plot the input and output signals in both the time and frequency domains.
