- Design a combinational circuit that takes 3-bit pattern as input and outputs binary code of bit position of the first 1' in the pattern reading from MSB (2nd position) to LSB (0th position).An additional output variable V is required along with binary code to indicate that the binary code is valid or note i.e., if the input pattern is '000' then the output V should be '0' to indicate that the binary code is not indicating the bit position of first 1' and we don't care about the binary code if V = 0. Design the required circuit using dual 4x1 MUXS and minimum additional logic.Available resources along with dual 4x1 MUXS are NOT gates, 2-input(AND, OR, NAND, NOR) gates.(b) Consider a voice signal from a analog telephone which needs to be digitized. Explain the steps involved in the conversion of analog to digital signal. If suppose the sampled analog values are 1V, 2V, 3.5V and 4.5V, use a 2 bit quantizer to digitize these values.
