NMJ20503 Digital Design Concepts Part 1

Digital signals differ from analog signals in that they have:

• Continuous values

• Random values

• Discrete values

• Constant values

What does 'bit' stand for in digital systems?

• Binary information transformation

• Binary information transition

• Binary digit

• Binary indicator time

In positive logic systems, a higher voltage level represents:

• Bit 1

• Bit 0

• Neither

• Both

The binary number system used in digital systems is based on:

• 10 digits

• 2 digits

• 8 digits

• 16 digits

A digital pulse waveform has two edges, the leading edge and the:

• Rising edge

• Trailing edge

• Left edge

• Peak edge

Which of the following factors does NOT affect the non-ideal behavior of digital pulses?

• Stray inductance

• Stray capacitance

• Pulse width

• Resistance

In a digital waveform, the time interval between the rising and falling edges is known as the:

• Pulse width

• Duty cycle

• Frequency

• Bit time

A periodic digital waveform repeats itself at a fixed interval called the:

• Amplitude

• Pulse width

• Period

• Duty cycle

The frequency (f) of a digital waveform is the reciprocal of its:

• Pulse width

• Duty cycle

• Rise time

• Period

The duty cycle of a digital waveform is defined as the ratio of:

• Rise time to fall time

• Pulse width to period

• Amplitude to pulse width

• Bit time to period
