For example, CD players are limited to 20-kHz rather than 22.05-kHz. What would happen with a 20-kHz sine wave? Would there be a beat frequency at a lower frequency?
It seems to me it would be very simple to connect a signal generator to a CD recorder and make some recordings of high-frequency sine waves. They could be viewed on an oscilloscope and also loaded into the computer and analyzed with a spectrum analyzer to look for the beat frequency. Have you tried anything like this?
I have a TASCAM CD-RW700 CD recorder, a Kenwood AG-253 low-distortion sine wave generator, a Tektronix TDS-2002 digital oscilloscope, and a computer with Sound Forge 7, which contains a spectrum analyzer function.
I don’t feel like doing the experiment tonight, but I might try it in the future. What frequencies do you think I should record and analyze?
Best regards,
John Elison
