ABSTRACT:
A bus compression apparatus for compressing data is provided to suppress an EMI signal and to simplify a data bus structure. In the apparatus, the voltage levels of the digital output signals are summed in accordance with the resistance values of the data compression circuit to produce a compressed analog signal. The compressed analog signal is transmitted through a bus lines to a data decompressor which reproduces the digital data in response to the voltage levels of the compressed analog signal.
