LIMITER DISCRIMINATOR

TM 11-7440-232-12/NAVELEX 0967-LP-275-5010

LIMITER DISCRIMINATOR

· The Limiter Discriminator (PIN 900-44756-

01) PCC module plugs into the modem shelf. It

converts fm binary or duobinary signals that represent

the information originally modulated by the distant

transmitter.

·The REC MODE operating control is located at

the front of the PCC module.

· All test pin-jacks are located at the front of the

PCC module.

DECODER ERROR DETECTOR

· Decoder Error Detector (PIN 900-44757-01)

PCC module plugs into the modem shelf. It regenerates

signals from the limiter discriminator to a serial-by-bit

NRZ form for driving a receiving data processor. It also

detects data pattern errors and loss of received signals

and provides outputs to peripheral alarm equipment.

· All test pin-jacks are located at the front of the

PCC module.

· The BIT RATE operating control and the

ERRORS indication lamp are located at the front of the

PCC module.

DIGITAL RECEIVER CLOCK

· Digital Receiver Clock (PIN 900-44760-01)

PCC module plugs into the modem shelf. It provides a

clock signal (phase corrected to regenerated data signal

from the associated receiver) for data retiming and for

external clocking functions.

· The BIT RATE operating control and the test

pin-jacks are located at the front of the PCC module.
