Latest Patents

Leslie R Sage holds a patent for a "Stereo Indicating Circuit." This invention is designed for indicating the reception of stereo signals in devices such as radio tuners and televisions. The circuit applies audio signals from the left and right output channels to respective limiting circuits, with the output signals being fed to an OR gate. When a monoaural signal is detected, the output from the exclusive OR gate remains low. However, when stereo signals are detected, a finite phase difference exists between the two signals, resulting in a high output from the OR gate. A Schmitt trigger drives an LED display to indicate when a stereo signal is being reproduced, providing users with a clear visual cue.
