Factoid: The rotary dial telephone actually makes use of digital technology whereas the touch-tone phone does not. The pulses generated by the rotary dial are fundamentally digital signals. The number of pulses generated is determined by how far the dial ring is rotated to the finger stop. Dial "1" and you generate one pulse; dial "9" and you generate a serial stream of nine pulses. It is the so-called modern touch-tone phone that uses analog technology in its dialing scheme. The DTMF (Dual-Tone, Multiple Frequency) audio is an algebraically combined analog signal.
