Q2. Design the given linear phase FIR filter using Hamming window. Also realize using linear phase structure. The desired frequency response is given as H₂(e) = Take alpha as 3 instead of 12 : /00/=/=/16/2 ; otherwise -ja12.
9. A multiplexer is a switching circuit that produces as its single output one of a set of inputs based on the value of some additional inputs called the controls. Given that 0, 1, 2, and 3 in two-bit binary are 00, 01, 10, and 11, respectively, draw a 2-bit multiplexer using the three basic logic gates with inputs xo, x1, x2, and x3, and two control inputs co and c1. Setup the circuit so that x; is the single output, where i if the value of the 2-bit integer (cico)2. NOTE: This is not a Boolean product; instead it's the binary representation of an integer where c1 is the most significant bit and co is the least significant bit.
