Abstract
We discuss the use of multi-rate FIR filters in radio frequency (RF) transient spectroscopy as well as the implementation challenges these multi-rate filters face when used in this application to reduce the sampling rate (decimation) and raise the sampling rate (interpolation). On a Texas Instruments TMS320-C30 DSP processor, all implementation measurements given here were carried out.
We have reported the application of multirate FIR filtering to radio frequency (RF) transient spec troscopy, and the implementation issues of these multirate filters for sampling rate reduction (decimation), and sampling rate increase (interpolation) in this application. These implementation issues include the transient response of the digital filters and the aliasing noise due to the decimation process in the passband and the stopband of the digital decimating filters. All implementation measurements reported here were performed on a Texas Instruments TMS320-C30 DSP chip.

Comments
The decimation and interpolation FIR filtering in the digital domain are used in the multi-rate digital approach, which employs a fixed sampling frequency to achieve the desired spectral width.
