What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
What is difference between ac series motor and dc series motor?
AC series motor uses the electric current to run the motor. Whereas DC motor uses the battery power to run it.AnswerAn a.c. series motor is termed a 'universal motor', because it will run on either a.c. or d.c. A.C. series motors are constructed in essentially the same way.
What are the uses of alternating current?
voltage can carry current a further distance.
What is a Stereo Power Amplifier?
A stereo power amplifier is simply a two channel power amplifier. You can runn it in a couple of ways; Stereo, mono or bridged. Stereo has a seperate left and right signal in and sepetate out. Mono is one channel in and both output channels reproducing the one signal in. Bbridged gives you the same as mono BUT it uses both channels as one output.
What are the uses of a conductor in high ressitance?
they are used to reduce the resistivity,owing to the fact that the conductor introduces current into the resistance
What is the difference between oscillator and feedback amplifier?
There are two differences: a) the amount of feedback you allow b) whether you wire a frequency-determining device into the circuit First things first: ANY amplifier circuit that uses feedback, which these days is most of 'em because feedback improves the quality of an amp's output, will oscillate if there's enough feedback. This poses a real problem because the more feedback you use, the better the amp sounds. Your challenge, therefore, is to make an amp that uses not quite enough feedback to oscillate. The other is equally critical. If you want oscillation you usually want it on a specific frequency. You can build an LC tank or a crystal into the circuit to determine the output frequency if you're building an oscillator; if you're building an amp you wouldn't do this.
Which is best positive feedback or negative feedback?
Obviously,it depends on the situation. consider a transistor amplifier.To minimize the change in collector current with respect to temperature,collector to base bias is used . This circuit uses a NEGATIVE FEEDBACK in order to compensate the rise in output current with temperature. But in order to achieve maximum gain, the same circuit can use POSITIVE FEEDBACK by connecting the amplified output to the input .
What are the advantages of series circuit?
The advantage of series is it uses less current than parallel
What are the mirror circuits?
ANSWER (current mirror) A current mirror circuit uses an amplifier to copy a current flowing in one leg of the circuit into another leg. One common arrangement uses four BJTs (two NPNs and two PNPs) and two resistors. Others are more or less complicated depending on linearity and temperature stability required for the application.
What is the difference between wien-bridge oscillator and phase-shift oscillator?
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback
What is the output impedance of common source amplifier circuit?
The output impedance of a common source amplifier circuit is typically high. This is because the common source amplifier uses a resistor to provide biasing, which results in a high output impedance. However, this can be mitigated by using a current source instead of a resistor for biasing.
What feedback does a close loop servo mechanism uses?
kidney
What type of power does a car amplifier need?
It has to be direct current, like what a car has or what a battery uses. It won't work plugged into an outlet at your house. That's Alternating Current (AC). So just hook it up to the positive lead to your battery and ground it to somewhere on your chassis.
How does a bass guitar function?
The bass guitar has two electromagnets at one end of the guitar, called Pick-Ups. These look like square metal panels with dots on them. The current from the amplifier gives the Pick-Ups a magnetic field. The vibrations of the strings affect the magnetic field and cause the current to fluctuate. This is a very simple system that converts the analogue vibrations of the strings into an analogue electrical signal. The amplifier contains a transistor which uses the weak current from the instrument to control the stronger current that powers the speaker.
What term a process the cell uses to control metabolism?
feedback inhibition
What are the uses of class b push pull amplifier?
Sound amplification. Servo control systems.
Methods the body uses to regulate muscle force?
One, the main, method is a process called feedback; and the process occurs in something called a 'feedback loop'.
