Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?

If the output power is 70% of the input power, then the output is roughly 1.55 dB down
compared to the input.
If the voltage at any point of the output waveform is 70% of the voltage at the same point
on the input waveform, and the input and output impedance are equal, then the output is
3.1 dB down (rounded) compared to the input.

What is audio output frequency?
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
What is the maximum frequency output can get from 555?
3MHz
What is the effect of low frequency on the voltage?
The frequency would decrease the gain and increase the output voltage
How does a frequency inverter work?
A frequency converter converts alternating current of one frequency to alternating current of another frequency. Generally it's used for controlling the ac motor speed by changing the supply frequency.
What is switching frequency?
switching frequency is the one which regulates the switching device in a electronic circuit,by which the output voltage can be determined or can be cntrolled
What is cut off region of an amplifier?
Amplifiers react differently to different frequencies. The amount that an amplifier reacts is usually measured in power (decibels). At a certain frequency (usually higher frequencies) the amplifier will react (output) only 50% of the power it is given (this works out to -3dB) this is the standard cutoff frequency and the cutoff region is anywhere below -3dB on a bode plot(This is a plot which shows the frequency input versus the response. These are very common when talking about amplifier characteristics).
What is output frequency of bridge rectifier?
twice the input frequency
What is audio output frequency?
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
How does frequency mixing take place in radio receiver?
The incoming frequency is fed to a transformer ( or IC chip). Another frequency is fed to that same place. The sums and differences are output. Differences are rectified to recover the modulated info.
Difference between natural frequency and resonance frequency?
In natural frequencies the output of the system will be less than the maximum level. In the resonance frequency the output of the system will be the maximum level.
Why the output of the envelope detector changed frequency when the audio frequency was varied?
answer for me please
How are FM signal generated?
There are several methods for generating FM signals but they all basically involve an oscillator with an electrically adjustable frequency. This type of oscillator uses an input voltage to affect the frequency of its output. For example, when the applied voltage increases, the oscillator output frequency increases and when the applied voltage decreases, the oscillator output frequency decreases as well. If no voltage is applied to the oscillator its output will be a signal at its centre frequency. The amount of frequency variations is deviated around the oscillators' centre frequency.
What is the maximum frequency output can get from 555?
3MHz
What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
What is frequency response?
Frequency response is the measure of the frequency of the output a device gives in response to a stimulus that it receives. The frequency response is a characteristic of the device.
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
What is transition frequency of a transistor?
The transition frequency of a transistor is the frequency in which the transistor will no longer provide any amplification or gain output. The frequency is out of the transistors's range.
