Spread Spectrum Diagram: Typical Frequency Hopping Pattern

The numbers above the waveform peaks (1 through 16) represent a typical frequency hopping pattern. The pattern is the result of a sequential preset algorithm designed to maintain synchronization between the Master and Remote radio modems.

Frequency Shift Key (FSK)

A typical digital data stream is illustrated with the equivalent carrier modulation form, as represented by a Frequency Shift Key (FSK) sine wave.

VS1 = Voltage Sent (Digital)

VR1 = Voltage Received (Digital)

VS2 VS2 also illustrate the line loss. (Note that the frequency amplitute is unaffected by data transmission distance.)
