Interpolated fir filter
Webcomplexity in digital FIR filters is the use of interpolated FIR (IFIR) filters [5,6]. The basic idea behind the IFIR filters is to remove quite a few impulse response samples, and next, recreating them through an interpolating filter. Such a procedure leads to a less expensive implementation of FIR filters. In addition, IFIR filters possess ... WebMar 23, 2024 · Figure 12: Block diagram of an Interpolated FIR filter. The shaping filter is based on a direct FIR, but what makes it different is the delay line – instead of having …
