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.

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.
How much of an object is imagined to be cut away in a half-section?
A quarter in order to expose half of the interior and half of the exterior in a single plane.
What is the area of grass cut by a machine called?
A lawn.
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.
Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
If the frequency of light is cut in half what will happen to the energy?
The energy of the light is directly proportional to its frequency according to the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. Therefore, if the frequency of light is cut in half, the energy of the light will also be halved.
What is a cone cut in half called?

What is to cut in half called?
To cut something in half is called "halving." This involves dividing an object or quantity into two equal parts.

What is a sphere called if you cut into half?
It becomes an hemisphere
What is it called when an object is cut in half and its exactly the same on both sides?
It is called symmetry. When an object is cut in half and both sides are identical, it exhibits symmetry.
If a wave is travelling at a certain speed and its frequency is cut in half what would happen to the wavelength of the wave?
it would become longer
What is a pie cut in two called?
Two half-pies.
If frequency of a sound wave is multiplied by 10 what happens to the wavelenth?
Frequency and wavelength have an inverse ratio relationship. When one doubles, the other is cut in half. When one is multiplied by 10, the other is divided by 10. The exact relationship is: wavelength = wave velocity/frequency.
