摘要： A method for amplitude modulating a carrier signal according to one embodiment includes splitting the carrier signal into first and second paths; phase modulating the carrier signal on the first path; phase modulating the carrier signal on the second path; combining the phase modulated carrier signal on the first path with the phase modulated carrier signal on the second path for generating an amplitude modulated output signal; and wherein a first feedback loop couples the amplitude modulated output signal to circuitry for phase modulating the carrier signal on the second path but not to circuitry for phase modulating the carrier signal on the first path, the first feedback loop being for reducing a residual phase variation of the amplitude modulated output signal. Additional systems and methods are also presented.

摘要： A first embodiment provides a process and system for simple, secure exchange of random numbers between two devices by combining a random number and a secret code (e.g., password) to generate a first challenge code, extracting the random number using the password at the second device, combining the first random number with a second random number, and returning the combination to the first device, which extracts the second random number from the second challenge code using its first random number. A CRC can be added to authenticate the sender. Another embodiment provides a system and method for generating a seedless pseudo-random number. The Yet another embodiment provides a system and method for generating data encryption coding with variable clocking.

摘要： A circuit for amplitude modulating a carrier signal includes a carrier signal input, circuitry for splitting the carrier signal into first and second paths, circuitry for phase modulating the carrier signal on the first path, circuitry for phase modulating the carrier signal on the second path, and circuitry for combining the phase modulated carrier signal on the first path with the phase modulated carrier signal on the second path for generating an amplitude modulated output signal. Feedback loops virtually eliminate residual phase shift and make the amplitude modulated output signal linearly proportional to the baseband signal.
