Abstract
A frequency shift keying system for transmitting a signal which is a function of supplied data, includes first and second frequency generators producing first and second frequencies which differ in value by an amount which is a function of the maximum baud rate of the data. A counter is responsive alternately to one and the other of the two frequencies supplied thereto as a function of the data values for alternately counting up and down between values which differ by some given amount. The counter output in analog form is the transmitted signal. This system is particularly adapted to minimum frequency shift keying.
