Latest Patents

One of his latest patents is titled "Method and apparatus for AC coupling." This invention involves a feedback circuit that detects a DC component in the coupled signal and adjusts a DC subtraction signal accordingly. In one embodiment, a digital signal processor (DSP) analyzes the coupled signal for any remaining DC component and controls the subtraction signal. The use of a DSP allows for dynamic control of parameters, including AC cutoff frequency, gain, and transfer function. Another embodiment provides accurately phase-matched AC coupling across two or more signal channels.

Another significant patent by Waite is "Time domain compensation for transducer mismatch." This invention features a two-channel real-time octave analyzer equipped with an adaptive time domain phase compensation filter. The filter's poles and zeros are programmably selected to counteract phase errors associated with any given pair of microphones. This precise matching of microphone phase characteristics is achieved through a transfer function determined using a pole/zero synthesis technique based on cross spectrum data acquired in an FFT spectral analysis of the probe microphones.
