Chapter 4, Question 19.
For digital systems, overall error must
include the quantization error caused
by the digital nature of the circuits.
Chapter 4, Question 21.
A voltage measurement error is caused
by the integration time window of a
digital voltmeter. This is a dynamic
error.
Chapter 4, Question 22.
If a low-impedance voltmeter is
inserted into a high-resistance dc
circuit, a instrument insertion error is
created.
