摘要： A dial signal generator supplied with dial data corresponding to a dial number, includes a dial data register (13) for storing the dial data, a decoder (81) 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-frequency (DTMF) system, a DTMF generator (14) for generating a DTMF signal from the row and column numbers generated by the decoder, and a dial pulse generator (16) for generating a dial pulse signal from the dial data supplied from the dial data register.

摘要： A decoding circuit comprises an m row by n column matrix arrangement of transmission gates (T₁₁, T₁₂, ...), wherein an output terminal of one of two mutually adjacent transmission gates in each column of the matrix arrangement is connected to an input terminal of the other of the two mutually adjacent transmission gates, input terminals of the n transmission gates in a last row are connected to a high voltage source (Vcc), output terminals of the n transmission gates in a first row are connected to a low voltage source, and gates of the transmission gates are connected so that all of the n transmission gates in a predetermined row are simultaneously turned OFF responsive to an n-bit input code having a predetermined value.
