integrated-circuit

Hello, I would like your suggestion on my first design Differential signal modulator [simulation attached]. Before jumping into design let me highlight my objective. I am differentiating a control signal of 1MHz and then modulating it with carrier frequency 15MHz(not limited to this specific...

Hello everyone. I came across while reading the opto-isolator technique used for electric isolation in embedded systems/ Integrated Circuits design that " Opto-isolator is not recommended for electric isolation in power applications IC's mainly due to its dV/dt sensitivity". So I would like to...

What is a single bit error event and non-corrected error event? And How is it implemented in ECC?

Hi all, I'm a math and physics major in my junior year. I am in a class called Scientific Instrumentation. The class requires that, by the end of the year, I must design and build a project on a breadboard. I decided that I wanted to build a breadboard that will play the melody of "Africa" by...

I bought tgis cheap bluetooth receiver that has a chip #AC1805E88767 or something like that with symbol of PI(3.1416) on it? I tried to search about this IC but nothing comes up. I tried to take a photo but the chip is very small. Does any of you know about this chip?

Hello everyone! I am looking for an Arduino Uno. If anyone has a used one, please contact me.

This is for my school project. So, I got my 74190 counter shows number like this 9-8-7-6-5-4-3-2-1-0-5-4-3-2-1-0-5-4-3-2-1-0-5-4-3-2-1-0 and so on. My questions: (1.) What can I do to change the output count down into 5-4-3-2-1-0-5-4-3-2-1-0 and so on (2.) When it changes 0 into 5 it moves so...
