What term describes a smooth varying signal produced by continuously changing the voltage or current in a circuit?
analog signal
What is a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
Why more current amplification in common emitter?
A bipolar transistor can be used in different configurations in linear electronic design. Most well known is the common emitter CE configuration with a base current as input signal resulting in a collector signal multiplied by the current gain factor. The second configuration is known as the emitter follower or common collector configuration. Here the input signal is in the form of a voltage between the base and the common connection. The output signal is found in the form of a voltage at the emitter with a relative low output impedance. The voltage swing at the input is almost as large at the output where the input impedance equals the product of the current gain factor and the emitter resistance. The third configuration is known as common base CB. Here the input current at the emitter almost equals the output current at the collector. The current gain is nearly equal to 1.
What is Hall effect and what is a Hall effect current transformer?
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
What is represented by 'A' in 'OA79' diode?
The symbol 'A' indicates that this device is made from germanium . as you may know germanium has less cut in voltage so this device is used for low power signal or for signal processing. also the leakage current or reverse saturation current of germanium is greater than silicon.
What is the meaning of I to p converter?
current to preesure converter means....current signal to pneumatic signal...
How the current signal converted into pneumatic signel?
A current signal is converted into a pneumatic signal with a Current-to-Pneumatic Converter. The converter allows a safe and proportional output to ensure a seamless conversion.
What is a direct current input signal?
DC current
What is the difference between voltage series and current series amplifier?
The main Difference between Voltage and Current Feedback Amplifiers is in the sampled(Output) signals. In Voltage feedback the sampled signal is voltage (Vf=Beta*Vo) where Vo is the sampled signal and for current feedback it is current signal (Vf=Beta*Io).
Why current limiting resistor is required?
to keep the signal awy from the dc limit ,, to ban the clipping of the signal
What is the operation of class c tuned amplifier?
that is where the end stage does not consume current when there is no signal to amplify. Opposite of a class A where the current is constant with any signal level (except saturation...)
What does changing the voltage or current in a circuit create?
an analog signal
What are the out put signal of current transformer?
kittys a w____R and so are you :)
An electric current that is varied to represent information is a?
Electronic signal.
Is this possible to convert voice signal into current?
Yes. That is what microphones do.
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
