Why is sinusoidal input and sinusoidal output preferred in frequency changers?

∙ 8y ago
Such a signal is optimal for use with electrical Transformers and household appliances. When you simply chop up DC current and send it through a transformer, that is a square wave, and square waves don't help the life of the transformer. Depending on the length of the cycle and the load, that could cause the transformer to get hot.

What is the fead back factor in oscillator?
The feed back factor in the oscillator refers to the output which is usually sinusoidal.
Can a low pass filter be used as an integrator?
When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
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
What is the difference between linear and nonlinear problems and how do you?
A linear circuit is an electric circuit in which, for a sinusoidal input voltage of frequency f, any output of the circuit (current through any component, voltage across any component, etc.) is also sinusoidal with frequency f. Note that the output need not be in phase with the input.
How the output characteristics of AC and DC generator vary from other?
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
What are linear wave Shaping circuits?
if a sinusoidal voltage is applied to linear circuit the output voltage is also sinusoidal in nature as far as the waveform is concerned the amplitude of input signal may change and there may be phase displacement between input voltages and output voltages

What is output frequency of bridge rectifier?
twice the input 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.
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
