Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

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 ...

The relationship between a signal’s constituent frequencies and the sampling rate used to quantize them is fundamental. As shown in Figure 1, sampling a signal that has a given spectrum creates a ...

Abstract: Aliasing of sampled monocomponent polynomial-phase signals is investigated. The results are applicable to general sampling schemes, and it is shown that aliasing can be avoided by sampling ...

Abstract: Abstract—A method for estimating the boundaries of the change of the sampling frequency of a signal is considered in terms of taking into account the main high-frequency components and ...
