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
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.
When was Cedarhurst Cut-off created?
Cedarhurst Cut-off was created in 1871.
What percentage of central frequency as bandpass for a narrow band amplifier?
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
What is cut off yield?
what is cut off yield? ans. cut off yield is the rate at which bids are accepted. bids at yield higher than the cut off yield are rejected and those lower than the cut off are accepted. the cut off yield is set as the coupon rate for the security. bidders who have bid at lower than the cut off yield pay a premium on the security, since the auction is a multiple price auction.
Why the te0 mode is the dominant mode in rectangular waveguide?
Because it has the lowest cut-off frequency (highest cut off wavelength) for a>b o

What is meant by beta cutoff frequency?
The beta cut off frequency is the frequency at which the current amplification of an amplifier transistor drops to three decibels below its value at 1 kilohertz. This is used in electronic engineering.
Can a waveguide have more than one cut off frequency?
yes it can have coz fc= c/2[(m/a)2+(n/b)2]1/2 therefore for various modes(which decide m,n) nd dimensions(a,b) of waveguide it will have different cut off frequency. A normal waveguide is used in the octave frequency range where only the fundamental mode can propagate.
What causes the gain of OP AMP to roll off after a certain frequency is reached?
A: Any amplifier will reach a frequency cut off point because of hindered circuit capability however the roll of bust be controlled especially when reaching oDB point must be at a -3 db roll off to prevent hi frequency oscillation
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.

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.
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
What is a magazine cut off switch on a browning a500?
From Browning's website - "allowing the shooter to retain shells in the magazine and eject a shell from the chamber without feeding from the magazine."
