DIGITAL FUNDAMENTALS 11TH EDITION
2026 SOLUTIONS MANUAL COMPLETE
QUESTIONS AND ANSWERS GRADED A+
⩥ Serial data transmission requires only two transmission lines.
Answer: False
⩥ Hybrid systems contain both digital and analog circuits.
Answer: True
⩥ The parallel transmission of digital data
Answer: requires as many signal lines between sender and receiver as
there are data bits.
⩥ The ________ system is also called the base-10 system.
Answer: decimal
⩥ The logic analysis of a digital circuit is used to determine how the
circuit responds to a binary (0 or 1) input rather than an actual input
voltage.
Answer: True
,⩥ The three most commonly-used numbering systems in the digital
system are ________, ________, and ________.
Answer: decimal, binary, octal, and hexadecimal

sequence?
Answer: 1011001_2
⩥ Each digit in the binary number system has three possible values.
Answer: False
⩥ A ________ diagram shows how the logic signal level varies with
respect to time.
Answer: timing
⩥ What is the name of a two-axis graph, with a horizontal axis
representing time, that displays pulse waveforms?
Answer: a timing diagram
⩥ The primary disadvantage of digital techniques is that the "real world"
is primarily analog.
Answer: True
