Thank you :rolleyes:

So this is a problem from the legendary Razavi book "Design of Analog CMOS Integrated Circuits" (Specifically, it is the problem 7.7 (c)). I got the solutions online but when I try to calculate the noise expression myself, I don't arrive at the same result. Lambda is assumed zero for neglecting...

Hello everyone, I am studying at the moment electrical stimulation of nerve fibers. I encountered this image which compares cathodal and anodal stimulation but illustrating the anodal block ocurring with cathode current. But I don't really get the point of the image, could someone clarify it...

What I am trying to achieve is a stabilized platform for a camera. This platform will be placed on top of a boat and will have to compensate for the boat movements in order to point always in the right direction. The final aim of this project is actually to record boat races so the "right...

Hello everyone, I am trying to build a 2-axis camera gimbal, which will control yaw and pitch. I have bought sensorless BLDC motors (GB280870KV) which I drive using SPWM. For knowing the camera orientation, I am using IMU sensors (accelerometer, gyroscope, and magnetometer) integrated on the...

Hi everyone, I'm kind of new in the QM world and I'm having difficulties understanding the superposition and the measurement principles together with the have function collapse. This is how I understand these principles: Superposition: While not measuring, the particle is in a superpsotion of...

That's my main problem lol. I don't know how to express the total phase difference for more than two sources.

That has to be the total phase diifference for any given number of sources in order for the intensity to be maximised.

Okey, I'll try to think. For constructive interference, the phase difference has to be 2mπ whereas for destructive interference, the phase difference has to be (2m+1)π. However, I can't see any wave in the problem interfering constructively or destructively.

Homework Statement Four identical wave sources (s1,s2, s3,s4 ) are located at the corners of a square. We know the phase at three sources: 0 at s1, π/4 at s2, π/2 at s3. Whet is the phase we have to give to s4 in order to have a maximun of intensity at the center of the square? Homework...

I have another different question regarding this same topic. As far as I've understood from my physics lectures, the normal force is a contact force which arises as a reaction of another force (third Newton's law) For example, in the case of weight, the Earth exerts a force (mg) on us and so...
