The Nyquist criterion states that a signal must be sampled at a rate of at least:
If a signal is sampled below the Nyquist rate, the result is:

Increasing the number of bits of an ADC from 8 to 10:
Quantisation error is:
In a weighted-resistor DAC, the resistors are binary-weighted so that:
A weighted-resistor DAC feeds each bit into the:
The main advantage of the R-2R ladder DAC is that it:
The raw output of a DAC is:
A low-pass reconstruction filter is placed on a DAC output to:
