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.
Why cut off frequency is called half power frequency?
Cut off frequency is that frequency at which the power output of the circuit reduces to half of its power in pass band. Power (P)= Current2 X Resistance. so to reduce the power by half we need to reduce the current by 1/sqrt{2} = 0.707 = 3 db. So it's also called half power frequency. http://enter4joy.com
What are cut-off and saturation points in a dc load line?
The cut-off point is the exact point where the load line crosses with the vector axis. The saturation point is the point where the load line intersects with the collector current axis.
Which element can cut glass?
water can cut through glass but only when at a very high speed and a thin stream
How do you find cut off frequency for a frequency response?
Different methods for different circuits. In a simple RC filter with a series R and shunt C, the time-constant T is equal to RC. The cutoff frequency is given by 1/(2.pi.T). So with 1 k-ohm and 0.1 uF the time-constant is 1000 x 1E-7 or 100 microseconds, so the cutoff frequency is 10,000/2pi which is 1592 Hz.
What are the application of low pass and high pass filter?
they are used in industries so to able you to work on particular frequency and cut the other for e.g if you are working for high frequency then low frequency will be cut and vise versa
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
The value of r when a transistor is biased to cut off is -?
Collector-to-Emitter resistance is high when the transistor is biased off.
Is a high pass filter and a low pass filter the same thing?
Yes, they are both filters. But their frequency characteristics are different. This is the main reason why they are given different names. A high-pass filter passes frequencies higher than its cut-off frequency, and stops those that are lower. A low-pass filter passes frequencies lower than its cut-off frequency, and stops those that are higher.

What is alpha cut of frequency?
it is the frequency at which the current amplification drops 3dB below its low frequency value.
Relation between cutoff frequency and bandwidth?
The relation between cut off frequency (fc) and band width is as follows: fc=Q*B.W where Q=(fL*fH)^1/2/(fH-fL) Q is quality factor. fL is low frequency. fH is high frequency.

What word is the charity collector cut off from saying in the story a Christmas carol?
Munifent
What happens to the speed of the waves if the frequency of the wave source is halved?
The wavelength of a wave would double if the frequency was cut in half. Wavelength=c/frequency where c equals the speed of light.
