- (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. Assume the range of sampled analog values from 0V to 5V. Provide the digitized values of this signal and draw the digital signal.Design a combinational circuit with the four inputs A,B.C, and D, and three outputs X, Y, and Z. When the binary input is odd number, the binary output is one lesser than the input. When the binary input is even number the binary output is one greate than the input. Implement the function using multiplexers with minimal input and select line.We want to design a digital circuit that converts Gray code (ABC) to Binary code (xyz). Set up a 8-to- 1 line multiplexer so that the output gives y as a function of ABC. "A" is given to the most significant bit of the control inputs of the multiplexer. "C" is given to the least significant bit of the control inputs of the multiplexer.
- 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.What is the value of the 8 digital bits that are represented as in the figure above if (Hint: the first bit is 1): a.
