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
Which of the following best describes serial data transfer?
Data is transferred all at once over multiple lines
Data is transferred one bit at a time over a single line
Data is transferred over multiple lines, one bit at a time
Data is transferred over a single line, all at once
Parallel data transfer differs from serial data transfer because:
It requires fewer lines
It transfers all bits at the same time over multiple lines
It transfers data more slowly
It sends data one bit at a time
Which of the following is an advantage of parallel data transfer over serial transfer?
Requires only one line
Transfers data faster
Requires fewer resources
Transfers data with less noise
Which of the following components is commonly used for storage in digital systems?
AND gate
Shift register
Decoder
Multiplexer
The conversion of analog signals to digital signals is achieved by a process known as:
Data transfer
Analog encoding
Analog-to-digital conversion
Digital filtering
