Examples of 'subband signals' in a sentence
Meaning of "subband signals"
Subband Signals: In signal processing, subband signals refer to signals that have been divided into multiple subbands or frequency components through techniques such as filtering or modulation. This approach allows for more efficient analysis, processing, or transmission of signals by isolating specific frequency ranges for targeted operations or enhancements
