---

---

APPARATUS

Pasco fourier synthesizer	202-17-D-1
oscilloscope with video camera	202
speaker	202

---

DESCRIPTION

The Fourier synthesizer generates two 440 Hz signals and eight harmonics.  Each has adjustable amplitude and phase.  Waves can be summed to produce square waves, sawtooth waves, etc.  Sum is displayed on scope and can be heard from speaker.

 

NOTES

Use synthesizer to trigger scope.

Refer to manual for harmonic content to synthesize square wave, triangle wave, sawtooth wave, train of pulses, rectified cosine wave, violin, clarinet, piano.
