Traditionally, in undersampling configurations, a bandpass-filtered signal would be sampled at a rate below the signals nyquist rate of twice the upper cut-off frequency of the bandpass filter. This ...
Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...
Primer on Nyquist and aliasing applied to the design of input filters for ADCs. Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies ...
