(b) A filter has an impulse response given by h[n] = 1 2 9 9 9 9 بیا ای } (1) Find and simplify the magnitude response of the filter. (ii) Find the group delay of the filter. (ii) A second filter has an impulse response given by gin = <u[n]-u Discuss whether both filters are effective in cleaning/de-noising a human voice audio signal corrupted by high-frequency noise. Explain the main difference between h[n] and g[n] when used to clean the noisy audio signal. (13 Marks)
