Class Information
Number: 375/343
Name: Pulse or digital communications > Receivers > Particular pulse demodulator or detector > Correlative or matched filter
Description: Subject matter where a signal to be demodulated is compared point to point with an internally generated reference signal which is constructed in such a way that it is at all times a prediction of what the signal to be demodulated should be at that time.
