Hi everyone
I am aiming to design a PIR sensor application with IRS-B210ST01 PIR sensor from Murata company but there is not enough information about the output voltage characteristic of sensor. Just:
Responsivity (500K, 1Hz, 1Hz) = 3.6mVp-p(Typ)
I wonder that any offset voltage or any...
It is not for noise filtering actually. These are basic band pass active filters. You can see details below link.

Hi everyone,
I am designing a sensorless type foc controller for the pmsm motors. I have a problem with speed controller parameters. I have no idea how can i tune the kp and ki parameters. Which motor parameters have affect on pi parameters?
Regards.
Dear friends, the question below asked in my latest signal processing exam. I have no idea about it and i could not find any solution in literature. Could you please help me finding out the answer. Actually i believe that i am quite good at signal processing until this question.
A voltage...
Could you please advice me a detailed reference to learn about the SVPWM. All the sources has same drawings and sentences. It is hard for me to imagine real world approximation.
Regards
I want to measure AC grid voltage by using an opamp circuit. I have just google it and could not found any solution. Do you have any circuit that you examined before.
Note: Output will swing 0-3.3V, Grid voltage max 260Vrms
Regards.
When i short connect probe pins to the same node (for example power ground) on the PFC circuit, oscilloscope displays some kind of noise against displaying zero voltage.
What cause this type of noise? Common mode or differential mode?
How one explain this issue.
I used passive probe and...
Hi friends.
Is there any one who can explain that why over-modulation occurs in space modulation technique?.
i think, it is possible to acquire the resultant vector by summing the two adjacent so why over modulation????

"Why are you responding to a post almost 6 years old?" Is it important?
"Why do you say that the above equation has no actual solution?" & "Why is crossing the x-axis a "must"? " Explain me that why we find the roots of an equation?
What is the "real world"? In real world, only "real numbers"...
Try that:
you want to solve f(x)=x^2+4 equation.
You see that there is no actual solution for this equation.No actual solution means to that "If you draw this eq. in your coordinate system it will not cross over x axis" But to handle and make it usefull crossing the x axis is a must for the...
Hi friends,
Last day i came across with a little weird problem.
I have built a IR receiver circuit for my project. In this project there is no communication problem in the 1-7 m distance range but if i put the remote controller very closed to the IR receiver (5-10 cm) there is no communication...
Topology : one master to multi slaves.
I intend to use parallel connection so i will use different SS pins for each SPI device. Connecting pins without pull resistors cause any bus-fight? I am not sure about that. I guess the pictures above for giving a basic idea.
Are you sure that any pull...
Thanks for the configuration info but main problem is using pull-up, pull-down resistor. Which pins(mosi miso sck ss) actualy need that? What is the purpose of using them.
Regards.
