Abstract: A constant frequency computer bus includes a sinusoidal wave generator that generates a sinusoidal wave. The sinusoidal wave generator is coupled to a reference line and a plurality of bus lines, and these lines transmit the sinusoidal wave. A plurality of amplitude modifiers are coupled to each of the bus lines. The amplitude modifiers modify the amplitude of the sinusoidal wave transmitted on the bus lines depending on whether a digital "1" or "0" is required to be driven on the bus lines. An additional amplitude modifier is coupled to the reference line to modify the amplitude of the sinusoidal wave transmitted on the reference line. A plurality of comparators are coupled to the reference line and each bus line. The comparators read the digital data on the bus line by comparing the amplitude of the sinusoidal wave transmitted on the bus line with the amplitude of the sinusoidal wave transmitted on the bus line. A digital output is generated based upon the comparison.
