Many realtime applications in signal processing consist of several pseudo-synchronous processes. Pseudo-synchronous processes are processes which must be run periodically, with very slight differences between their periods. A typical example is the transmitter and the receiver of a modem. Under a certain condition (processing time condition, see below) the term pseudo-synchronous can be extended to periodic processes with completely different periods. The period TN of the process PN is determined by the synchronism with which the process Pn must exchange the input information and output results with the external devices. For a modem, this synchronism is the baud time which is locally generated for the transmitter and determined from the received signal for the receiver.
