electrical engineering

1. design a 7 tap FIR low pass filter using the frequency sampling method.THe sampling rate is 10 khz and the cut off frequency is 3 khz

2.design a second order IIr bandpass filter with 9mhz, a 3 db bandwidth of 150 khz centred at 1.5 Mhz

3.design a IIr filter (using a first order butterworth lowpass prototype fil

ter ) with sampling rate of 8000hz ,lower cut ff frequency of 2400hz and upper cut off frequency of 2600hz.

i need answers for these examples ASAp
