Solution:

There are two bulbs and two switches in a room. A bulb gets turned ON only if one of the two switches is turned ON, not both. Which logic gate does this switching operation resemble?

XOR

XNOR

NOR

Solution:

A 10-bit analog-to-digital (A/D) converter is used to digitize an analog signal with a 0.5 V range. The maximum peak-to-peak ripple voltage that can be allowed in the DC voltage is:

nearly 100 mV

nearly 50 mV

nearly 25 mV

nearly 5 mV

Solution:

The output expression for the Karnaugh map shown below is:

BD̅ + BCD

BD̅ + AB

B̅D + ABC

BD̅ + ABC

Solution:

In order to check the CLR function of a counter ____________

Apply the active level to the CLR input and check all of the Q outputs to see if they are all in their reset state

Ground the CLR input and check to be sure that all of the Q outputs are LOW

Connect the CLR input to Vcc and check to see if all of the Q outputs are HIGH

Connect the CLR to its correct active level while clocking the counter; check to make sure that all of the Q outputs are toggling
