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.
