) Tuned amplifiers cannot be used at low frequencies because of the requirement of very large value of L in the tuned circuit [1]. This requirement of high value of L at low frequency is impossible because the size and weight of inductors become exceedingly large and Q becomes very low.

Why electrolytic capacitors are used for frequency response of BJT as amplifier?
It can take a lot of capacitance to present a low impedance to a low frequency. Electrolytics offer lots of capacitance for a low price.
What should I do to install a low pass filter if my amp doesnt have one?
A: Installing a low pass filter is only required if the frequency are not there or to eliminate the low frequency, If it is an audio amplifier you never will need low frequency since your mine hears cannot hear those frequency.
How do you convert low frequency to high frequency with a circuit?
You typically create a DC power supply from the low frequency, and use that to run a high frequency oscillator and amplifier. If there needs to be a relationship between frequency in and frequency out, often there is a divider running on the high frequency side in combination with a phase locked loop synching up to the low frequency side.
Frequency response of bjt amplifier?
All amplifier typically exhibit a band-pass frequency response. The cut off frequency in the low end is usually determined by the coupling band bypass capacitor .and the high frequency limit is typically determined by internal capacitances in the transistor itself.
What type of antenna is used in cellphone for FM?
LNA - Low Noise Amplifier
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-
What is the low frequency gain in operational amplifier?
low frequency gain will be 20log(Vo/Vin)
Why electrolytic capacitors are used for frequency response of BJT as amplifier?
It can take a lot of capacitance to present a low impedance to a low frequency. Electrolytics offer lots of capacitance for a low price.
Why do you need small signal amplifier?
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
What should I do to install a low pass filter if my amp doesnt have one?
A: Installing a low pass filter is only required if the frequency are not there or to eliminate the low frequency, If it is an audio amplifier you never will need low frequency since your mine hears cannot hear those frequency.
What is a common base NPN amplifier?
A common base NPN amplifier is used for high frequency applications as the base minimize oscillations at high frequency, separates the input and output. In a common base NPN amplifier the voltage gain is high, relatively low input impedance and high output impedance compared to the common collector.

What is an instrumentation amplifier used for?
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
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.
How does korn make that low frequency boom?
Mostly the guitar's D tuned 7 string guitars and David silveria's drum tuning
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.
