  1. The Sallen-Key realization of a 5.25-MHz, three-pole Butterworth filter has a gain of 2 V/V and can drive 75 Ω back-terminated coax with an overall gain of 1 (Figure 1). Used to reconstruct component-video (Y, Pb, Pr) and RGB signals, this ...
  2. Izhar Fareed Using this low cost Project one can reproduce AUDIO from TV without disturbing anyone. It does not use any wire between TV and headphone. In place of pair of wires it uses invisible Infrared light to transmit audio signals from TV to ...
