We present the continuous flow system specification formalism (CFSS). This formalism provides a digital computer approach to the representation of continuous systems based on a broad interpretation of the sampling concept. Continuous flow models permit to represent systems with both time-varying and multirate sampling. The equivalent dynamic system of a CFSS model is defined. Based on the CFSS formalism a multirate integration method is developed.
