Using the inputs on a computer’s sound card is an old trick to fake a very simplistic, AC coupled, slow oscilloscope. You can get DC operation by desoldering a couple capacitors, but if the sound card ...
The advent of inexpensive standardized 16- and 24-bit audio I/O hardware for personal computers inspired a rush of oscilloscope simulating applications. Many of these “Sound Card Scopes” are quite ...
The project aims to create a digital GLCD oscilloscope with a speed of about 650,000 samples per second or showing around 60 KHz frequency signal. This 650KSPS digital GLCD oscilloscope contains some ...
