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.
Claims2
A wide dynamic range pulse to pulse rate converter comprising in combination:
- first means for linearly converting an input pulse rate to a first linear analog output;
- second means for linearly converting said input pulse rate to a second linear analog output;
- and
- means for superpositioning said first and second analog outputs.
