t is very importantto keep the relation between the impedances constant because thedetecting current depends very markedly on the value of theexternal impedance in the plate circuit. The w^ave impressed on the input of the detector can be a sparksignal wave or a modulated wave which is interrupted.… … FiG. 208. ducing modulated waves. The output of this oscillator systemcan then be passed through an omnigraph to produce the signals.The R.M.S. of the input can, as before, be measured by means of aresistance r and galvanometer G (Fig. 208). The use of the receiver shunt makes it possible to…
