Which of the following methods are used in sampling rate conversion of a digital signal?

Multirate Digital Signal Procesing topics include: Factor decimation and multirate digital signal processing. Multirate digital signal processing (DSP) is a technique that changes the sampling rate of a signal to increase the efficiency of signal processing operations. It's a key part of designing digital frequency converters.  Multirate DSP uses multiple sampling rates within a system. The two basic operations in a multirate system are: Decimation: Decreases the sampling rate, also known as down-sampling Interpolation: Increases the sampling rate, also known as up-sampling  Multirate...

Multirate digital signal processing (DSP) is a technique that changes the sampling rate of a signal to increase the efficiency of signal processing operations. It's a key part of designing digital frequency converters. 

Multirate DSP uses multiple sampling rates within a system. The two basic operations in a multirate system are:
Decimation: Decreases the sampling rate, also known as down-sampling
Interpolation: Increases the sampling rate, also known as up-sampling 

Multirate DSP matches the sampling rate between the baseband and high-frequency processing side, especially in down conversion. 
Multirate DSP systems are sometimes used for sampling-rate conversion, which involves both decimation and interpolation.
