PC oscilloscope
Designed by Bojan Banko he write: was doing an ultrasound project when at one point I couldn’t move forward without an oscilloscope.I’m hobbyst in electronics, and I don’t really need a real oscilloscope. I don’t want to spend money on it and I don’t have enough space in my electronics corner for it.So, I took a look what is offering at the Net. I found a great (and free) solution: Winscope. It’s using the sound card and that’s all you need. The problem with this solution is that you just can’t get the sample rate more than 44kSamples/sec. That’s enough for audio signals(<15kHz), but not for 40kHz ultrasound signals. You need around 10 samples per cycle (or more) of the signal you are measuring to get any decent waveform to actually view.
