This kit facilitates students to see decoding of original encoded signal sent through PCM Transmitter Kit. The receiver kit “phase locks” to the input pulse stream to derive clock information. Moreover, by the use of pseudo-random binar y sequence, the synchronization between transmitter and receiver is established. Exhaustive manuals are provided along with the kit, which provides detailed experimental procedure and complete circuit diagram explanation of the kit.

FEATURES:
• 2 channel Time Division Multiplexed PCM receiver.
• Real-time operation using fast mode and examination of data and control signals decoding using LED’s in slow mode.
• Low pass filters for reconstruction.
• Single bit error detection, when odd or even parity is selected in the transmitter.
• Single bit error detection and correction when Hamming code is selected in the transmitter.
• Various test points provided on-board.
• Switch Faults.
• Provision for external audio signals through Audio Output Kit.
