Gandalf Supermodem: Gandalf, a Canadian company, was the first to produce a 9600 BPS modem that could work on dial-up phone lines. The modem contained more computing horsepower than most modern computers. It worked by playing chords of tones for 1/40 second. Averaging the signal over such a long time eliminated most of the effects of static. At the receiving end, Fast Fourier transforms analysed the chords back into the component tones. Most modern high speed modems have started with this idea and refined it. The ingenuity of modern modems such as the Telebit Trailblazer is extraordinary. The only problem is, all these schemes are proprietary, so different brands of modems cannot talk to each other.
