1)in cc configuration we use to get the low output impedence
where as in ce we use to get the high output impedence.
2)in cc amplifier we use to have the voltage gain equal to unity
where as in ce amplifier we use to have the high voltage gain.
3)in cc amplifier there is high power gai which is used for impedence matching
where as in ce amplifier due to the high voltage gain the impedence matching is
less impossible.
What else can I help you with?
Can an am rf amplifier at 27 mhz work on FM at same frequency?
Yes, but it will be less efficient than one designed for FM.
Is The carrier frequency is usually lower than the modulating frequency?
when the frequency is low , energy will be obviously low. To increase the energy of the signal we need to increase the frequency. This is achieved by multiplying the message signal with the carrier signal (with high frequency).
Why high frequency is used in communication than low frequency?
High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.
Why piezo crystal oscillator used?
Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.
Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
What is bi-wiring of speakers?
This is where the low-frequency driver, or woofer, is wired to a separate amplifier than the high-frequency driver or drivers. Also called bi-amping.
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
Frequency response curve of RC coupled amplifier?
at low frequency less than 50hz the voltage gain decreases with decreasing frequency and at mid frequency{50hz to 20khz} the voltage gain is uniform because resistor value are independent of frequency change and at the high frequency votage gain falls.
Can an am rf amplifier at 27 mhz work on FM at same frequency?
Yes, but it will be less efficient than one designed for FM.
What is class c tuned amplifier?
Class C tuned amplifier is a large signal tuned amplifier that amplifies high power signals of the radio frequency range. The amplifier is said to be Class C if the output cycle obtained is less than half a cycle of the full input cycle. This means the transistor remains active for less than half a cycle so that only that much part of the input waveform is reproduced at the output with amplification. For the remaining part, the transistor remains inactive.
Do ultraviolet waves have a high or low frequency?
That depends what you call "high" or "low". The frequency of ultraviolet waves is higher than that of visible light; lower than that of x-rays.
What are the waves that have high frequency also have high?
High frequency waves also have high energy. This means that waves with shorter wavelengths (higher frequency) carry more energy than waves with longer wavelengths (lower frequency). Examples of high frequency, high energy waves include gamma rays and X-rays.
If wave amplitudes are equal will high-frequency waves carry more or less energy than low-frequency waves?
if wave amplitudes are equal ,will high frequency waves carry more or less energy than low frequency waves
Which will have more energy a high frequency waves or a low-frequency wave?
High frequency waves will have more energy than low-frequency waves. This is because energy is directly proportional to frequency in waves - the higher the frequency, the higher the energy.
Meaning of high sounds?
High frequency (high pitch) sounds have a higher frequency than those of lower pitch. The air molecules of a high frequency sound, vibrate back and forth much more frequently.
Do light waves move at a lower or higher frequency than visible light?
they are a high frequency
What is amplifier and what is the general circuit of amplifier?
An amplifier amplifies voltage or current. The most basic amplifier consists of a transistor where a signal is fed into the base and is output to the emitter or collector. For simple, low frequency applications (not RF), it may be simpler to use an operational amplifier (op amp) than designing your own amplifier. Also, the data sheets provide very helpful schematics for creating an amplifier. A very common one is the 741; these are also fairly cheap.
