CONSTITUTION:In the transistor (Tr) amplitude limiter which controls an amplitude limiting level by an emitter current, variable element z is connected as a collector load to the collector of Tr6 of the amplitude limiting circuit composed of transistors 5 and 6 supplied with signals of input ...
The circuit is nothing but a simple transistor switch with a relay at its collector as load. Five switches (S0 to S4) arranged in series with the current limiting resistor R2 is connected across the base of the transistor and positive supply rail. Another five switches (S5 to S9) arranged ...
To prevent transistor 10 from saturating in its on condition a current limiter comprising a tunnel diode 13 and a resistor 15 is connected in the emitter circuit. Referring to Fig. 3, the value of resistor 15 is made numerically equal to the value of the negative resistance region of the ...
The transistorized noise limiter circuit depicted in the diagram below can be used to solve this problem. Using potentiometer R3, both the signal and the noise are sent to amplifier Q1 in this circuit. These waveforms are amplified identically by transistor Q1, however diodes D1 and D2 restric...
