Define MUX and DEMUX. Where we use mux and demux system? How toc reate a 16:1 MUX by using 4:1 MUX with a truth table and draw a diagram for this MUX

None

Show each step clearly ... 1. Compute the 8-bit two’s complement for -79 and -23. 2. What are the negative decimal numbers represented by the bytes 0xF2 and 0x83? 3. Show how each of the following signed, decimal integers would be stored in 8-bit two's complement code. Give your answer in hexadecimal. Must show the steps to get the result. (part a) +99   (part b) -1

Alamouti scheme is an example of  A. Space time coding B. MIMO C. None of these

Digital logic design Solve it with drawing and simulation lab I need them both to have the full solution. And thanks Design counter that counts from 00 to 59, using the IC 74LS90 ripple counter and use two 7 segment display to display the result count. You can also use 7447 binary to 7-segment Display Decoder.

1. Decide whether of the following statements is true or false. a. When only input 1 contact is activated, there is an output. b. When only input 2 contacts is activated, there is an output. Inputs 2 Output

ANSWER ALL THE FOLLOWING QUESTIONS. For each of the following 12-bit PCM, determine the 8-bit compressed code, decoded 12-bit and the decoded analog voltage for a resolution of 5 mV: 100001000000 110011001010 100000010010 000000100000 010000000000 000000000100

For the function f = w'2w'3 + w1w2 Work the problem with a 4-1 multiplexer and with a 2-1 multiplexer. With the 2-1 multiplexer implementation you can choose a select input (say w1) and try to express the output f in terms of the data inputs (w2 and w3).
