CSE 120 Quiz 1

Most digital circuits represent binary values using

0v and +5V

What is the period of a clock waveform whose frequency is 4 mHZ

250 s

What is the frequency of a clock waveform whose period is 20 microseconds

50 kHz

The boolean equation for an OR gate is

A + B = X

Which logic function can be implemented by connecting an inverter to the output of a NAND gate

AND

Which logic function is represented by the equation ABCD=X

AND

If one input of an OR gate is HIGH while the other is a clock signal, the output is

HIGH

If one input of an AND gate is LOW while the other is a clock signal, the output is

LOW

Which logic function can be implemented by connecting an inverter ti the output of an OR gate

NOR

(T/F) An NAND gate with inverters connected to each input behaves like an OR gate

TRUE

(T/F)Can you construct an XOR gate using only AND/OR/NOT gates?

TRUE

The boolean equation for a NAND function

X = (AB)'

Which gate can be used to generate a true output if an odd number of inputs is true

XOR

If both inputs of an AND gate are normally HIGH but one of them momentarily dips LOW, the output will

momentarily dop LOW

The rising edge of a digital clock occurs when

the signal changes from LOW to HGH

During which interval in an AND gate will the output be HIGH

when A and B are 1

LOW(or binary 0) in a digital system typically corresponds to

0 V
