Abstract

In a DSB-QC type of modem receiver made to operate at various bit rates within 12000 bps (bits per second) and 4800 bps at a 2400 baud rate, the receiver input signal is sampled using a CK1 clock at a baud rate multiple (say, 12000 cps (cycles per second)). The samples are then processed by a signal processor which derives therefrom the received symbol and a corresponding group of data bits decoded each baud time. These bits have then to be forwarded (serialized) toward the corresponding terminal (DTE) at the adequate bit rate, e.g. 9600 bps, without any error. The present multiformat serializer performs the bit distribution of the data bits with a minimal extra hardware for processing any of the bit rates even though the circuit description will be given for a 9600 bps rate.
