Based on your own words, enumerate and briefly discuss some applications of flipflops

Finding Standard SOP and K-Maps (see next page!) Convert each expression to standard SOP form: ( A + B)(C+B')  ABD                  (4-term expression with A, B, C, D)  A + BD           (4-term expression with A, B, C, D)

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

Remember, binary subtraction is implemented by adding the 2's complement value of the subtrahend. In the following predictions, be sure to negate the subtrahends. Set #1 SUB Set #2 SUB A= 7 B= 2 A= B= S= Cout= Overflow Set #3: SUB A= B= 1 3 S= Cout= -8 4 Overflow A3 B3 S3 A₂ S3 A₁ B₂ B₁ B3 B₂ Ao Bo S₂ S₁ So A3 A₂ A₁ Ao B₁1 Bo S2 S₁ So S= Cout= Overflow Set #4 SUB A= -6 B= -5 S= Cout= Overflow A3 B3 A3 B3 A₂ S3 B₂ A₁ S3 S₂ S₁ So A₂ В1 Ao Bo B₂ В1 A₁ Ao Bo S₂ S₁ So

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).

Design a Moore state machine with one input x, and one output y. The output is normally 0, but becomes 1 whenever the machine detects the sequence "x = 0", "x = 1", and "x = 1" on the three consecutive rising edges of the clock.  Sketch a state graph for your design. Write down the state table for your design Come up with a state assignment Find the excitation logic for D flip flips Sketch a diagram of your final design.
