Multirate Signal Processing

Multirate signal processing involves handling signals at different sampling rates within a system to optimize performance. By switching between high and low sampling rates, it reduces computational load, bandwidth, and power consumption while maintaining signal quality. Techniques like decimation (downsampling) and interpolation (upsampling) allow efficient processing in applications like audio, telecommunications, and multimedia. Essentially, it’s about intelligently adjusting how often signals are sampled and processed to improve efficiency without compromising accuracy.
