Aliasing
Aliasing is a distortion that occurs when a signal is sampled at a rate insufficient to uniquely represent its frequency content, causing fr...

Decimation
Decimation is the process of reducing the sample rate of a discrete-time signal by retaining one out of every M samples, where M is the inte...
I
-
Interpolation
Interpolation is the process of increasing the sample rate of a discrete-time signal by inserting new samples between existing ones, typical...

Nyquist Rate
The Nyquist rate is the minimum sampling frequency required to represent a bandlimited signal without aliasing: it equals twice the highest ...
O
-
Oversampling
Oversampling is the practice of sampling or processing a signal at a rate significantly higher than the Nyquist rate (at least twice the sig...

Polyphase Filter
A polyphase filter refers to the multirate filter structure obtained by decomposing a prototype FIR filter (or, less commonly, an IIR filter...

Sampling Rate
Sampling rate (also sample rate or sampling frequency, commonly denoted Fs) is the number of samples taken per second from a continuous-time...

Sigma-Delta Modulation
Sigma-delta modulation (also called delta-sigma modulation) is a technique for converting analog signals to digital (or digital to analog) b...
