How does a capacitor act as a filter?
The cutoff frequency of filter depends upon the value of capacitor and resistance. Therefore, below cutoff frequency or above this frequency, capacitor allow to pass all other frequencies.

The attenuation in wave guides near the cutoff frequency is?
zero
What is the significance of the cutoff frequency in an RL circuit?
The cutoff frequency in an RL circuit is the frequency at which the output signal power is half of the maximum power. It is significant because it determines the range of frequencies that can pass through the circuit effectively, affecting the overall performance and functionality of the circuit.
What is the -3dB cutoff frequency?
A: It is a standard statement to signify that the amplitude is one half.
What is band rate?
ANSWERED MY MUHAMMAD WALEED SHAIKH first of all we have to know that about band,so band is range of frequency which we have selected for example:we have a low pas filter it frequency always started from initial or 0 HZ upto cutoff frequency and here remember that cutoff frequency we will have to select after cutoff signal is rapidly down now about band rate so your signal is band at certain rate is called band rate.
How value of c is calculated in an RC filter for a given value of r?
Time constant = R C C = time constant/R R = time constant/C When used as a filter, Cutoff frequency = 1 / (2 pi) R C R = 1 / (2 pi) (cutoff frequency) ( C ) C = 1 / (2 pi) (cutoff frequency) ( R )
What do you mean by 3 dB cutoff frequency?
3db frequency is the frequency at which the value in the graph is reduced by 3db level It's also known as the half-power point.
Give the difference between LPF and HPF?
LPF is a low pass LTI filter which passes the low frequency signals and reduce the amplitude of the signals with frequencies higher than the cutoff frequency. HPF is high pass LTI filter which passes the high frequencies and reduce the amplitude of the frequencies lower than filter's cutoff frequency.
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.
How the capacitor set lower cutoff frequency limit?
A capacitor totally blocks DC current (it's an open circuit to it). The higher the frequency, the less resistance (impedance) the capacitor has.
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.
