Loudspeaker Resonant Frequency Meter
For laptop or PC
This system is designed to facilitate the determination of loudspeaker resonant frequencies. What components do you need for this? A good variable oscillator, an amplifier, and meters for reading the frequency and the voltage.
The oscillator here is based on the function generator described in the April 1995 issue of Elektor Electronics.
