Frequency Shift Keying Data Bus Communication System.
Abstract
A data bus system utilizing a frequency shift keying transmitter and receiver to a multiple channel data bus communication system. A transmission line is utilized to connect the transmitter unit to the receiver unit. The frequency shift keying transmitter unit utilizes binary logic levels which drive a voltage controlled oscillator to generate different frequencies for different logic levels and a zero crossover which is used to avoid generation of harmonics during transmission.
