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??
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...
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
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
hello
i need some help and am confuse about it now..
after calculating the math.. 1.67531519 x 10 power of negative 8.. if i change to nano it is 16nf???
1.515761363 x 10 power of negative 10, if i change to nano is 15nf???
what about changing to miro??? confuse with the 10 power of...
hello
I would like to know what is the different between half wave rectifier circuit and peak detector circuit..
as what i know from half wave.. it only take the positive wave only..
then what about peak detector ??
Hello
May I know what is the difference between
Confidence Interval for Population Mean (μ) when σ Known vs Confidence Interval for Population Mean (μ) when σ unknown..
any example to show me??
Hello
I'm doing a question in induction motor now.
formula for Induced torque is Pgap / Ws.
i have found the Pgap, but in order to find Ws, i need frequency to find ns..
so my question is, how to find frequency with only given 10hp and four pole
Op Amp -- what is the slew rate limitation?
Hello
i would like to what is the slew rate limitation??
and why it is good to have higher slew rate???
thanks

Hello
I need to do bode plot..
but i not to sure how to use matlab..
i need this 1 / (a + bs)s
num = 1
how to key in the den to get (a + bs)s..
i try different way and i can't get 1/(a+bs)s
hope to get help
