Project #PC16
Symphony of Sounds PC
OBJECTIVE: To see the waveforms for a complex signal.
The Symphony of Sounds project combines waveforms from the
Music, Alarm, and Space War integrated circuits. Build the circuit
shown. If continuing from the previous experiment then close the
Winscope program and run it again, to reset the settings. Click on
the On-Line button to activate, and turn on the switch (snap part
S1). Press the press switch (S2) and wave your hand over the
photosensitive resistor (RP).
Due to the combination of sounds, the waveform is complex. Set
Winscope to the settings shown, or as you prefer.
