  • Digital tone generation based on difference equations
    Patent number: 5121350
    Abstract: A method of generating pure and decaying sinusoidal waveforms is readily implemented on arithmetic processors found in telecommunications circuits. The method is based on finite-difference equations and provides a sequence of signals having a high degree of spectral accuracy compared with presently-used methods. The sequence of signals can be generated in real-time without templates (ROM-stored patterns) because the method requires only two multiplications (16,18) and one addition (12) for each signal value generated in the sequence. The method finds application in dual-tone, multi-frequency (DTMF) telephone dialing systems.
