Clock modulation systems
First Claim
1. A dock modulation system comprising:
- a clock modulator generating Bit Rate Agile (BRA) clock shaped, clock modulated signals;
a modulator filter band limiting the said modulated signals;
a signal transmitter transmitting the clock modulated bandlimited signals;
a receiver and demodulator for reception and demodulation of clock modulated signals; and
a Bit Rate Agile (BRA) demodulator filter for filtering the received signals said demodulator filter having intentionally miss-matched filter parameters to that of the modulator filter.

Abstract
Shaped Clocked (SC) and Clock Modulation (CM) systems, signal generation-reception, processing and CM implementations. Systems having a first and second shaped clock signal and providing shaped clocks to a selector switch and to a signal transmitter. The selectable clock signal parameters include symmetrical and non-symmetrical shaped clock signals, shaped filtered continuous clock signal patterns, shaped encoded clock signals, variable rise and fall time clock signals, clock signals having shaped adjustable on and off duration, multilevel and shaped clock signals and asynchronous clock signal information transmission means. The Clock Modulation (CM), Shaped Clocked (SC) systems, also designated as Feher Keying (FK) systems or FK processors are also used in conjunction with cross-correlated quadrature and also non quadrature modem systems as input drive signals to FM VCO based systems, to SSB to VSB to DSB-SC to QAM, and/or to coded systems.
