Motorola MC3417 continuously variable slope delta modulator-demodulator IC is used as 16-kHz simplex voice coder-decoder for systems requiring digital communication of analog signals. Clock rate used depends on bandwidth required and can be 9.6 kHz or less for voice-only systems. Analog output uses single-pole integration network formed with 0.1μF and 10K. Report covers circuit operation in detail for various applications.- Continuously Variable Slope Delta Modulator/Demodulator, Motorola, Phoenix, AZ, 1978. DS 9488
