... CLK band. If, for instance, an LTC1164-5 operating with a 100kHz clock and 1kHz cutoff frequency receives a 98kHz 10mV input signal, a 2kHz 56µV alias signal will appear at its output. When the LTC1164-5 operates with a clock-to- cutoff frequency of 50:1, aliasing occurs at twice the clock frequency ...
