Latest Patents

One of his latest patents is titled "Digital circuit for the introduction of dither into an analog signal." This invention involves an electronics circuit designed to digitize an analog audio data signal into a digital equivalent signal. It introduces digitized Nyquist dither data into the digital signal, significantly reducing the need to remove this data before converting it back to an analog signal. The circuit includes a pseudo-random number generator that produces a series of digitized Nyquist dither bits, which are added to the digital equivalent signal. This process enhances the quality of the audio signal by ensuring a more accurate representation of the original analog input.
