GAIN CONTROL FOR A HIGH DEFINITION TELEVISION DEMODULATOR |
摘要 |
A demodulator for a high definition television receiver includes a first circuit element which receives a signal, and is operative in a first arrangement to produce an output signal having a first dynamic range, and operative in a second arrangement to produce an output signal having a second dynamic range different from the first dynamic range. A second circuit element is arranged for optimally processing a signal having a substantially predetermined fixed dynamic range. A gain control circuit is coupled between the first and second circuit elements, and produces a signal having the substantially predetermined fixed dynamic range. |
