When designing bass reflex loudspeaker cabinets, it is necessary to measure the resonance of the speaker to an accuracy of about 1%. To do this, you need an audio oscillator and a frequency counter.

Frequency multipliers are essential to generate a high frequency, low phase-noise signal from a low frequency, high performance oscillator. Figure 1 shows a phase noise comparison between a signal ...
