What methods are used in sampling rate conversion of a digital signal?

Explanation: Sampling rate conversion of a digital signal can be accomplished in one of the two general methods. 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.

What is sampling rate conversion in DSP?

Sample-rate conversion is the process of changing the sampling rate of a discrete signal to obtain a new discrete representation of the underlying continuous signal.

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.

Which of the following has to be performed in sampling rate conversion by rational factors?

Which of the following has to be performed in sampling rate conversion by rational factor? Explanation: We emphasize that the importance of performing the interpolation first and decimation second, is to preserve the desired spectral characteristics of x(n).

Which conversion type needs a sampling of a signal?

The object of A/D conversion is to convert this signal into a digital representation, and this is done by sampling the signal. A digital signal is a sampled signal, obtained by sampling the analogue signal at discrete points in time.

What is 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 multirate structures for sampling rate conversion?

The two basic operations in a multirate system are decreasing (decimation) and increasing (interpolation) the sampling-rate of a signal. Multirate systems are sometimes used for sampling-rate conversion, which involves both decimation and interpolation.

What is interpolation in DSP?

In the domain of digital signal processing, the term interpolation refers to the process of converting a sampled digital signal (such as a sampled audio signal) to that of a higher sampling rate (Upsampling) using various digital filtering techniques (for example, convolution with a frequency-limited impulse signal).

Which of the following is an method for implementing an FIR system?

Explanation: There are several structures for implementing an FIR system, beginning with the simplest structure, called the direct form. There are several other methods like cascade form realization, frequency sampling realization and lattice realization which are used for implementing and FIR system. 4.

Which of the following operation has to be performed to increase the sampling rate by an integer factor H?

1. Which of the following operation has to be performed to increase the sampling rate by an integer factor I? Explanation: An increase in the sampling rate by an integer factor of I can be accomplished by interpolating I-1 new samples between successive values of the signal. 2.
