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...

currently i need to turn on my IGBT. i measured Vge, it shown 8.25V, but my design requirement of Vge is 15V. i did some research, do i need to add in parasitic capacitances to my IGBT??

may i know what is snubber circuit?? and what is the different between having snubber circuit vs without subbers circuit..

Hello i would like to know, how does LM324 create a sine wave after the output of the op amp?? thanks

hi.. do you have any links that i can read?? thanks

hi.. thanks for the reply.. may i know how does it effect the limits the bandwidth go the signal? i still very confuse about this point.

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 Homework Equations The Attempt at a Solution there is will be the trade off between power and bandwidth. Vdc and Vm...

hello. what is the condition to use product detector?

Hello 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

Vectors -- dot product and cross product? Hello may i know when to dot product and cross product?? both look to same to me..

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

when is the condition for use of product detector??

as in the i just want to know the theory of it

What will happen to product detector and envelope detector when modulation depth is increasing?
