A DTMF generator includes a high gain differential amplifier having a noninverting input, an inverting input, and an output. A first audio oscillator connects to the inverting input of the amplifier via a first series of frequency determining components. A second audio oscillator connects to the ...

A dial signal generator supplied with dial data corresponding to a dial number, includes a dial data register for storing the dial data, a decoder for decoding the dial data supplied from the dial data register to thereby generate corresponding row and column numbers based on a dual tone multi...
Each channel consists of a bandsplit filter for extracting the tone of interest and attenuating the other tone; a comparator for comparing the output of said bandsplit filter with a threshold value; and an adaptive threshold generator for generating said threshold value adapted to the amplitude of...
