please solve using matlab code

By the method of locating poles and zeros, design a digital filter that only passes the band with a central frequency of 1200 Hz, the sampling frequency of the filter is 10 kHz. clear anim(1200*380)/6000 conv -0.98condang) +0.98*sindang,12 -0.98"cond fang) -0.98* sind canu a. Determine the transfer function of the filter. 2^2 - 1 2*2 - 1.429 2 + 0.0603 b. Generate a signal x (t) = 2 cos 1000 pt - 4 sin 2400 pt + 6 cos 4000pt, calculate the gain and phase angle of the filter frequency response at the signal frequencies. c. Generates a random noise signal with amplitude 1 and average 0. d. Get the filter output when the noise polluted signal x (t) enters. e. Modify the filter to have a filtered signal closer to what it should be. Explain your reasoning for this modification.
