Answer:A
Which of the following is the first method proposed for design of FIR filters?
A. Chebyshev approximation B. Frequency sampling method C. Windowing technique D. None of the mentioned
Explanation: The design method based on the use of windows to truncate the impulse response h(n) and obtaining the desired spectral shaping, was the first method proposed for designing linear phase FIR filters.
