Abstract
Abstract A system for converting a variable pulse rate input signal to an analog output signal responsive to the rate of the input. A plurality of parallel channels are utilized in the conversion process, each covering a different portion of the desired dynamic range of the system, with the outputs superpositioned in a weighted fashion for producing a combined output.
