- Relevant Equations
- Vc = 1/jwC
Question
Answer;
Answer;
thank you for the feedback, what do you mean by 2nd guessing? for `How can XL + XC = 0 ?` what should I do for that question? Did I got it wrong for my calculation?Baluncore said:2nd guessing will not educate you, nor solve the problem.
At the frequency where L and C are resonant, there will be a deep notch with V = 0.
How can XL + XC = 0 ?
I see, I ll change itBaluncore said:Notice the sign of the reactance.

How about now? I use -1/wC for Xv, is it okay?Baluncore said:Notice the sign of the reactance.

Thank you very much, I see, I think my answer is still not correct. I ll try to learn your suggestion.Baluncore said:I think you need to brush up on your complex arithmetic.
https://en.wikipedia.org/wiki/Complex_number
V = E * ( 0 + j Xv ) / ( R + j Xv )
So you need to divide an imaginary by a complex.
The amplitude of an analog filter refers to the magnitude or strength of the signal passing through the filter. It is a measure of how much the filter affects the amplitude of the input signal.
The amplitude of an analog filter is typically measured in decibels (dB), which is a logarithmic unit of measurement. It is calculated by taking the ratio of the output amplitude to the input amplitude and then converting it to a logarithmic scale.
The amplitude of an analog filter can be affected by several factors, including the filter's frequency response, the type of filter (e.g. low-pass, high-pass, band-pass), the cutoff frequency, and the order of the filter. Additionally, the components used in the filter's design can also impact its amplitude.
The amplitude of an analog filter can attenuate or amplify the input signal, depending on the frequency and characteristics of the filter. For example, a low-pass filter will attenuate high-frequency signals, while a high-pass filter will attenuate low-frequency signals. The amplitude of the output signal will also depend on the filter's gain and the input signal's amplitude.
Yes, the amplitude of an analog filter can be adjusted by changing the filter's parameters, such as the cutoff frequency or the filter's gain. It can also be adjusted by adding or removing components in the filter's design. However, it is important to note that changing the amplitude of a filter can also affect its other characteristics, such as its phase response and frequency response.
