ABSTRACT:
Pulse modulation circuitry which receives n binary data bits and generates a rate/width pulse modulated signal representing the binary value of the received data bits. The lower order m of the n bits generate a rate modulated signal having a number of pulses equal to the binary value of the m bits. The remainder of the n bits width modulate the rate modulated pulses. Each least significant bit increase in the binary value of the received date bits increases the width of a rate modulated pulse by a predetermined amount.
