SOUNDSCOPE

If you own a PC computer, you can use a sound card as an oscilloscope to display a electronic signals.(Sound card have an A/D 16 bit converter
with 48 kHz of sample rate ).For safety reason, I have create a circuit, that protect the sound-card from a high voltage.This is enabling or amplify or reduce the signal inclusive calibration of voltage levels.
This circuit has one restrict - you can measure only AC signals.
