Is there a way to build an accurate oscillator producing a sine wave for a single fixed frequency in the 500 Hz - 5 kHz range, using relatively common components?
- Any frequency within this range would be fine (although somewhere around 1 kHz would be preferred), as long as this frequency can be accurately obtained in practice, within 1% or better of the theoretical value.
- Some distortion of the sine wave is not critical, as long as the fundamental frequency is at the specified value. (In fact, other wave forms would be an acceptable comprise if a sine wave is too difficult.)
- The only power supply available is 0-5V DC. The output should also be within 0-5V (although not necessarily reaching those values).
