hi... i need some understanding of optocoupler chip after doing so much of research.
currently am doing buck converter circuit to observe the switching performance of IGBT..
i test my circuit with (PWM chip > High Side driver > power circuit). when i power on the whole circuit.. i can't...
1. Homework Statement
how the overall power becomes lesser when one side band is taken away by the bandpass filter and also how it limits the bandwidth of the signal
2. Homework Equations
3. The Attempt at a Solution
there is will be the trade off between power and bandwidth...
I am trying to learn something and really hope to get some help..
i know the use of envelope detector.. but when to use product detector?
i know product detector will be more expensive than envelope detector.. please help
May i know to obtain fourier series representation for trigonometric and complex form base on magnitude spectrum and phase spectrum??
what i found is that to get trigonometric form is from phase spectrum, but i don't know how.. can anyone help
