New use for scopes
Bored test and measurement experts have managed to find an alternate and entertaining use for oscilloscopes.
The scope was connected to a pc soundcard (in X / Y mode – with the right channel connected to the X and the left connected to the Y input) and the effects on the 'Youscope' are spectacular.
According to the designer, the reason the effects look so unusual is that most soundcards have a low pass filter at about half of the sample rate.
Not convinced? You can try it yourself, by downloading the waveform and music. You will never look at an oscilloscope in the same way again.
