Product Description

The 7406 data formatting and carrier modulation transmitter trainer is a digital communication system which efficiently explains all communication processing steps involved in digital transmission and reception of analogue signals. Various digital modulation techniques such as ASK, FSK, PSK, DPSK, QPSK etc can be implemented using combinations of the 7406 and 7407 trainers.

In order for this unit to work correctly the 7407 carrier demodulation and data reformatting receiver is required.
