- Building the Tone Generator -
1. Tone Generator
The 555 timer chip is an integrated circuit which is used to create a vibrating signal.
2. Signal Generator
The LM348-D is an integrated circuit which is the basis for a Signal Generator. It is a more sophisticated option to the Tone Generator.
3. Adding Notes
The tone generator can be made into a synthesizer by modifying it so it can produce a variety of tones. The synthesizer also needs a keyboard.
Determine the pattern of notes produced by pressing individual keys and key combinations (write it down). Use an oscilloscope to measure the frequencies of all the notes your synthesizer can produce.
