ABSTRACT:
A circuit arrangement for processing sampled analog electrical signals, each sample being in the form of a current, includes apparatus for combining, in predetermined proportions, the input sample current in a present sample period with current(s) derived from input sample current(s) in one or more preceding sample periods. Apparatus is also provided for deriving the processed output signal from the combined current produced by the combining apparatus in successive sample periods. The circuit arrangement is formed by a plurality of circuit modules, for example, scaling, memory, and integrator modules, each of which may be capable of processing only unidirectional currents. To enable easy interconnection of the modules, each module is arranged to receive and deliver unidirection currents and to generate internally bias currents to enable conversion from bidirectional to unidirectional currents and vice versa.
