He has made significant contributions to the field of electronics, particularly in the development of advanced audio and frequency control systems. With a total of 2 patents, his work has had a lasting impact on the industry.

Latest Patents

One of his latest patents is titled "Adaptive multiplex blend control for stereo decoder to maintain signal." This invention involves an integrated circuit stereo decoder that includes a blend control input terminal. The DC control voltage on this input terminal determines channel separation. During multiplex FM reception of multi-path signals, the signal strength signal has AM and DC components. By detecting and amplifying the AC component and adding it to the DC component of the signal strength signal, in phase opposition, the presence of multi-path can be made to reduce the resulting combined signal strength signals. This, in turn, is connected to the blend control terminal, allowing the presence of multi-path to reduce separation, thereby maintaining signal-to-noise ratio and reducing distortion.

Another significant patent is the "Automatic frequency control system." This invention pertains to a superheterodyne FM receiver that features a manually tunable local oscillator, which is electronically voltage tunable over a small range. It includes a frequency discriminator that provides signal voltage and automatic frequency control (AFC) voltage in response to a received FM carrier. The system incorporates an electronic bipolar switch that responds to either positive or negative AFC voltage of greater than a predetermined value, effectively grounding a point of the AFC circuit that applies AFC voltage to the local oscillator. Additionally, it features an interchannel noise detector that provides a grounding signal for the same point of the AFC circuit.
