Frequency modulation is a special case of angle modulation where the instantaneous frequency of a carrier is varied by an amount proportional to the modulating signal amplitude.
Our latest invention allows Tropian to maintain precision in the output signals from our transmitters by constantly measuring the actual angle modulation produced, and to correct any errors almost immediately.
6,219,394, entitled Digital Frequency Sampling and Discrimination, is a key Tropian accomplishment in the area of strongly-nonlinear angle modulation technology.
