I found a chart of musical notes in frequency and according to it, C1 is 32.70Hz. So with an oscillator, what value resistor and/or capacitor would i need to get it to oscillate at 32.70Hz or 33Hz?
RicharO is correct. There are some subtleties about musical notes that are not recognized or understood by many people.Keep in mind that resistors and capacitors are not very accurate or stable over time and temperature. In addition, real components will never have the values calculated. For many cases these errors are not a problem.
For music, the correct frequency must be quite accurate and stable. Notes in the musical scale are only a few percent apart. If notes are played one at a time a small error can be tolerated (at least to my untrained ear). When more than note is played at the same time the frequency errors are much more apparent. This is because the notes beat against each other and create more frequencies.
I will stop here and let someone that has real musical knowledge explain things better.
Which oscillator. With additional active components (transistors, opamp, logic gate, etc.) you can set a square wave oscillator frequency with one resistor and one capacitor, but it will not sound like a musical note. For a sine wave oscillator with no inductors, you need a minimum of 3 resistors, 2 capacitors, and a light bulb.ISo with an oscillator, what value resistor and/or capacitor would i need to get it to oscillate at 32.70Hz or 33Hz?
32.7is 99.09% of 33 so the resistor value needs to be appropriately smaller.I found a chart of musical notes in frequency and according to it, C1 is 32.70Hz. So with an oscillator, what value resistor and/or capacitor would i need to get it to oscillate at 32.70Hz or 33Hz?
