Multirate Signal Processing Definition: Signal processing which uses more than one sampling rate to perform operations Upsampling increases the sampling rate Downsampling reduces the sampling …

Jun 17, 2025 · Multirate DSP is a technique used in digital signal processing to change the sampling rate of a signal. It involves using multiple sampling rates to efficiently process signals and improve …

Used to change the rate of a signal. When two devices that op-erate at di erent rates are to be interconnected, it is necessary to use a rate changer between them.

A basic operation in multirate signal processing is to decompose a signal into a number of subband components, which can be processed at a lower rate corresponding to the bandwidth of the …

Consider oversampling the signal at, say, 64 times the Nyquist rate but with lower precision. Then use multirate techniques to convert sample rate back to 44.1 kHz with full precision.

Simulate the output of a sample-and-hold system by upsampling and filtering a signal. Decimate, interpolate, or change the sample rate of signals, with or without intermediate filtering. Change the …

Multirate systems have gained popularity since the early 1980s and they are commonly used for audio and video processing, communications systems, and transform analysis to name but a few.

Jan 20, 2026 · This course provides an in-depth treatment of both the theoretical and practical aspects of multirate signal processing. The course begins with a review of discrete-time systems and the …

Remark: Consider downsampling as a two stage process: first, we discard information which leads to aliasing in the frequency domain; next we contract the signal in time, stretching out the spectrum.

Multirate Signal processing can improve system performance and reduce costs in applications ranging from laboratory instruments, cable modems, wireless systems, satellites, Radar, Sonar, and …
