Communication Systems Lab Trainer

comm

Benchmark CommLAB-T – Communication systems Laboratory Trainer is a hardware-software platform to teach concepts of analog communication systems. The hardware consists of a Digital to Analog Converter (DAC) for transmission and an Analog to Digital Converter (ADC) for reception.  Transmitter & receiver are connected through BNC cord to form a complete communication system.
