We need to use synchronous TDM and combine 20 digital sources, each of 100 Kbps. Each output slot carries 1 bit from each digital source, but one extra bit is added to each frame for synchronization. Answer the following questions: a. What is the size of an output frame in bits? b. What is the output frame rate?

None

witch of the following is howZ = X - Y calculated in an ALU?  Assume unsigned integer codes.   A Z = X + 1's complement(Y) + 1   B Z = X + 2's complement(Y) + 1   C Z = X + 1's complement(Y) - 1   D Z = X + 2's complement(Y) - 1

4. Three input channels need to be multiplexed using TDM, Their bit rates are 120 kbps, 80 kbps, and 40 kbps, respectively, (a) What is the required output bit rate for the TDM? (b) How to set the relative size of each time slot in one frame? (e) What is the minimum frame size and the corresponding frame rate?

Assume that we have a 4-bit ALU. List the inputs and outputs in binary for the ALU if we are using it to determine the subtraction of A = 6 10 and B = 7 10 · Note that ALU operation is 102. Input: a = (dotsdots) b = (dotsdots) Output: Zero = (C) Result _) Overflow = (C) 7. Assume that we have a 4-bit ALU. List the inputs and outputs in binary for the ALU if we are using it to determine the subtraction of A = 610 and B=710. Note that ALU operation is 102.
