Delta modulator utilizing a duty cycle circuit |
| abstract |
A delta modulation system for encoding and decoding an analog input signal. The encoder includes a comparator to generate an encoded digital signal representing the analog input signal and a duty cycle circuit to represent the slope of the analog input signal. The decoder utilizes a similar duty cycle circuit which operates on the encoded digital signal received in order to translate the encoded signal into an analog output signal. |
