单词 | grid limiter |
释义 | grid limiter [`grid ´lim·ǝd·ǝr] ELECTRONICS Limiter circuit which operates by limiting positive grid voltages by means of a large ohmic value resistor; as the exciting signal moves in a positive direction with respect to the cathode, current through the resistor causes an IR drop which holds the grid voltage essentially at cathode potential; during negative excursions no current flows in the grid circuit, so no voltage drop occurs across the resistor. |
