The sampling rate conversion process is undertaken by the multiplexer at the output by selecting every mt l samples. in this example, the efficient realisation is illustrated for a signal which is interpolated by l = 3 and decimated by m = 2 samples.
Ppt Lab 4 Sampling And Rate Conversion Sampling Powerpoint The document discusses different approaches for sampling rate conversion of continuous time signals. it describes the standard approach using decimation and interpolation, and also introduces orthogonal and oblique projection re sampling methods. Splitting interpolation and decimation into multiple steps avoids using computationally difficult narrowband filters. by up downsampling in smaller steps, you can use simpler wideband lowpass filters in each stage. As discussed in the lectures, sampling rate conversion (src) is a process of converting a discrete time signal at a given rate to a different rate. this process can be implemented with a linear time varying system with a complexity that is a function of the src factor. In many practical applications of digital signal processing, one is faced with the problem of changing the sampling rate of a signal, either increas ing it or decreasing it by some amount. the process of converting a signal from a given rate to a different rate is called sampling rate conversion.

D rate conversion decimation reduce the sampling rate of a discrete time signal. low sampling rate reduces storage and computation requirements. interpolation increase the sampling rate of a discrete time signal. Master rational sampling rate conversion. learn the theory of upsampling, downsampling, and filtering, and discover efficient polyphase implementation techniques. In this lab students are going to be exposed with sampling down rate conversion called decimation and up rate conversion is called interpolation by integer factors. In this paper, we present a survey on linear phase finite impulse response (fir) based sampling rate conversion. many different fir based src solutions exist, such as classical fir,.
