Sound Card Oscilloscope and Multivibrators
What can a sound card oscilloscope do for me? This is the question I get asked a lot and I usually say something along the lines of "No engineer can do without one". Not many people find this very helpful so I've built a simple astable multivibrator and applied the oscilloscope to it. In trying to explain what the waveforms mean I hope to answer the question better.
