    I need to detect the number of rotations of a spinning magnet. I have measured the magnetic field strength oscillating around += 0.9 Gauss (see attachment). Most hall effect sensors with built in amplifiers and comparators don't have operating points in this range so I need to design one using an analog output hall effect sensor and op amp. However, I'm open to other design suggestions. Requirements: - Digital output indicating a rotation of the magnet - Low power (~50 uA @ 3.3v) - Minimal part count - Low cost part selection - SPICE simulation or some kind of verification of design Example design: Analog hall sensor (e.g. DRV5053) -> Amplifier -> Comparator with hysteresis (e.g. TLV320x) -> Digital output

The main idea of the article: in the digital relay protection and automation terminals, the settings are set in almost the same way as in analog electromechanical relay protection devices. This is an atavism. In digital relays, it is possible to refuse current-dependent steps, a limited set of types of characteristics and set an unlimited number of current-independent steps (conditional settings), you can set separate settings to busbars in directional current protections, ...

    Hi, I have programmed an imc controller for a mimo nonlinear system in Matlab simulink. The system has 3 outputs and 3 inputs. The control runs so far. However I have 2 problems 1. 2 outputs are controlled to the setpoint. However, one output does not reach the setpoint. x1 does not reach u1. 2. if I add a disturbance, the system does not control and the simulation hangs. Here I noticed that the choice of the filter is important. However, I can only control one output with the correct choice of filter. x1 does not reach u1 and x3 does not reach u3
