Hi all,
I want to use reference module that distribute universal reference signal. The aim is for audio/video phasing.
But, I would like to ask, what is the reference signal input need to generate the universal reference signal? In the input specification mention "Passive Loop-Through",what it...
Hi all,,
I would like to use thermistor as inrush current protection circuit..
The input DC voltage is 24V and maximum inrush current that had been decided is 8A.
So, I use thermistor which have R25 = 5Ohm (> 3Ohm)
I had found this thermistor,,
but how i ensure that the thermistor won't be...
Hi goldsmith, thank you for reply
actually,this is the 1st time i make an amplifier, for my final project i choose class D amp because i think it is interesting.
i use three level modulation, and in power stage i use H-bridge with MOSFET.
and for modulator i use noise-shaping coding technique...
Hi all,
currently, i'm making a filter-free class D audio amp for my project.
i measure output THD from my amp using spectrum analyzer and get THD = 1.84%. quite high.. :-(
and i also measure THD from my function generator as an input in my amp. and i get THD = 0.32%.
my question is, is my THD...
hello everyone...
i need help about how to build RS485 connection between a computer with micro controller ATmega8535.
and I want to know, in C# if I have command serialport.RTSEnable = true, so what's going on??
pin RTS become high logic or low logic??
and if RTS pin has high logic, what the...

i think it happen because the output of your 741 circuit is in saturation voltage of Vee.
your output should be 0V, but min and max output from 741 can't produce voltage same with Vee and Vcc.
the maximum output of 741 approximately is (Vcc - 2) V and minimum output is (Vee + 2).
so your output...
Hi Ratch, i usually see the transfer function represent as a function of jw..F(jω) or F(s) in Laplace..
i never see tf write like yours, so at first it makes me confuse..
if tf present as a product of zeros and poles form, i think it is more easy to consider the frequency response of the circuit...
thank you Ratch,
i see now..now,i understand your solution..:-)
i didn't aware that if i multiply both numerator and denominator with j,i got same solution with you in your equation #6..
:-)
Hi Ratch, i have see your attachment, actually i rather confuse with how you solve that equation..in your result i see an j is alone,but i consider in equation j must follow with jωC2..
I solve your equation using my way...you can see in my attachment..
I solve the transfer function of the...
yes i agree with emresel, Fourier is frequency analysis. Laplace too.
Fourier analysis usually used to solve problem in LTI system.
but Laplace can do something that Fourier can't do.
For example, Laplace can analyze unstable system which Fourier can't do..
Laplace can use for analyze the...
yes, i agree with FvM,
the transfer function is Eo/Ei = -1/k*(R3/R4 + 1/jωR4C2).
but i think there is an effect because of resistance of potensiometer which is parallel with C2 and R3.
the output resistance of opamp is small,but in that circuit the output resistance will be Rp1 parallel with...
