G4m0rvx

Analog 2.0

Overview

The design requirements are as follows: (all implemented)
(1) Input impedance >= 10MΩ;
(2) Voltage amplification factor 250 times;
(3) General heart rate signal frequency band width is 0.05-100Hz;
(4) Design the required DC power supply by yourself ;
(5) The input waveform can be clearly displayed on the oscilloscope;
(6) The circuit adopts a modular design, and the input and output of each module need to have separate test points to facilitate testing and connection.

July snow attracts people
In the hot summer, people in many areas are experiencing the test of high temperatures, but in the Zheduo Mountain in Sichuan, a rare scene of "snow in July" was staged. At 7:00 a.m. on July 13, 2011,
What is the difference between an operational amplifier and a comparator?
[align=left][color=#333333][color=#191919]Operational amplifiers and comparators are similar in appearance and drawing symbols, so what are the differences between them and how to distinguish them in
Newbie question, how to make TCP socket connection in pocket pc 2003 se emulator (someone help me)
I started a server locally and tried to write a program to run on the PDA. I tested it locally and used TCP socket to connect to the local server (127.0.0.1). I used the Pocket PC 2003 SE emulator but
Analysis of capacitor failure
1. The explosion-proof valve opens: Phenomenon: the internal pressure increases and the internal temperature rises. Reasons: during use, overvoltage is applied, the ripple current is too large, revers
I'm new to FPGA and I need help. Can I use this stopwatch when I copy it to my experimental board? If there is an error, how can I fix it?
