Aliasing
At the filter’s output, alias signals will appear when
signals at the filter’s input have substantial energy very
near the clock frequency or any of its multiples (2 • f
3 • f
operates with a 100kHz clock and has a 99kHz, 10mV
signal at its input, a 1kHz, 10mV alias signal will appear
at the filter’s output. Table 5 shows details.
