Chapter 7
Digital Filters Using Frames
7.1 Theory
A
S discussed in Chapter 6, using frame-based processing greatly increases the efficiency
of DSP programs. The CPU performing the signal processing algorithm is only inter-
rupted at the end of a frame rather than at every sample. In this chapter, we will show
how frames can be used for time-domain digital filtering similar to the filters we discussed
in Chapter 3.
Recall that a time-domain implementation of a digital filter involves an iterative calcu-
lation of the filter’s difference equation. The only change in this chapter is that we will be
dealing with our samples a frame at a time rather than a sample ...
