Multi-Channel Sampling

Multi-channel sampling is a technique used to efficiently capture signals that span a broad range of frequencies. Instead of sampling the entire signal at a very high rate, it splits the signal into multiple narrower frequency bands, each handled by a separate channel. Each channel samples its specific band at a lower rate suitable for that frequency range. Afterwards, the data from all channels is combined to reconstruct the original, wide-band signal accurately. This approach reduces the overall sampling rate and data processing requirements while preserving important information across all frequencies.
