Which of the following about 5 step systematic designing procedures is wrong?

In recursive decoder design, to design a 6-to-64 decoder, how many 3-to-8 decoders do you require?

The implementation of Multiplexers is usually accomplished by utilising which of the following functional blocks?

The use of decoders is most commonly used to simplify

You have 5 hard drives sending information onto a single data bus. Which of the following component is most useful, in determining which input gets onto the main data bus?

What is the unsigned 2s complement of 8bit integer 10101100?

What is the signed 2s complement of 8bit integer 01100000

If your input X is fed into a 8-to-3 priority encoder, and the output of the priority encoder except for the validity bit is fed into 3-to-8 decoder for output Y, then

If your input X is fed into a 4-to-16 decoder, and the output of the decoder is fed into 16-to-4 standard encoderfor output Y, then

To be able to process 5channels 8bit inputs to a single data bus, assuming you only have the multiplexers below (as well as other types of functional blocks), what kind of multiplexer should be used?

How many output ports should a 16input priority encoder have?

To implement an alarm system with master control switch, which of the following component is most suitable?

To implement 2 switches that can control a single light, where regardless of what the other switch's state is, a switch on its own could turn the light on and off, what kind of component should be used?

A telephone switchboard is to be designed, so that N incoming calls could be directed to correct telephone. Disregarding conflicts, which of the following components should be used?

A component is needed to translate rotatory positional information to numerical values. Positional information can be retrieved sensors placed in the rotatory disk, when the machine is rotated to a position, the sensor at that position will generate a signal in the high voltage area. Which component is most suitable for such translation?

A fuel tank has a vertical array of sensors at different heights, each of them which will generate positive signals when it detects fuel at their level. Which of the following components should be used to translate that into NUMERICAL fuel tank status information?

Which of the following components is most suitable for determining if two values are the same?

How can one implement a 2s complementer?

How should one perform signed multiplication using unsigned multipliers?
