| 释义 | > as lemmasleaky-grid detection d. Retaining electric charge only with gradual loss; connected to or having a high resistance that acts as a ‘leak’; leaky-grid detection, detection in which the signal is applied to the grid of a valve through a series capacitor and a resistor (the latter being connected as a grid leak or in parallel with the capacitor).

Scott-Taggart Wireless Vacuum Tubes (ed. 4) viii. 167 A leaky grid condenser may be connected in the grid circuit. 1934 Jrnl. Inst. Electr. Engineers 75 298/2 Leaky-grid detection is used in this receiver. 1962 D. F. Shaw Introd. Electronics ii. 35 A leaky capacitor..in which the leakage resistance is represented by a shunt. 1968 Radio Communication Handbk. (ed. 4) ii. 17/1 Any d.c. voltage developed across the grid leak by the rectification of a modulated or an unmodulated signal will thus constitute a negative bias for the grid and the anode current in the triode will fall... An excessively strong signal will tend to bias the valve beyond the cut-off point, and therefore a leaky-grid detector ceases to function satisfactorily when the input voltage is too great. 1969 R. G. Middleton Transistor Television Servicing Guide ix. 105/1 A leaky transistor, such as 22..increases in temperature. < as lemmas |
