What do you mean by fractional sampling rate conversion?
Sampling-Rate Conversion By A Rational Factor
The change of the sampling frequency by a rational factor L/M, sometimes called the fractional sampling rate alteration or resampling, can be achieved by increasing the sampling frequency by L first, and then decreasing by M.
What are the two methods used for sampling rate conversion?
One method is to pass the signal through D/A converter, filter it if necessary, and then to resample the resulting analog signal at the desired rate. The second method is to perform the sampling rate conversion entirely in the digital domain.
What is meant by sampling rate conversion?
Sample rate conversion is the process of changing a stream of discrete samples from one sample rate to another stream at a different sample rate. A sample rate converter, or resampler, is a module that implements sample rate conversion.
How do you change the sample rate in Matlab?
To change the sample rate from 44.1 to 48 kHz, you have to determine a rational number (ratio of integers), P/Q , such that P/Q times the original sample rate, 44100, is equal to 48000 within some specified tolerance. To determine these factors, use rat .
