Application Description
Description
FourierSynth Fourier Synthesiser allows students, engineers and musicians to study quantitatively the Fourier components of periodic waveforms. Real-time superposition of harmonically related sinusoids upto 15th harmonic can be viewed with the built in Time Domain display or alternatively viewed on an Oscilloscope connected to the audio stereo output. Those musically inclined can choose to listen to any two sinusoids or the sum of all selected sinusoids.
Features:
Select Sine and Cosine from fundamental to the 15th harmonic . See how convergence to the ideal improves with more components
Fundamental frequency adjustable from 50Hz to 1kHz
Individually control amplitude and On/Off state of each harmonic
DC term available on iPad display
Select from a range of 10 preset waveforms Square, Triangle, Sawtooth, Amplitude Modulation, Impulse, Half and Full Wave Rectification
Monitor waveforms externally on an Oscilloscope or Listen to audio output
Choose which sinusoid or ‘sum‘ appear on display or audio output
Listen to musical chords and hear the effects of phase change on their sound
Use the full range of Swipe, Tap, Pinch, Tap&Hold Gestures
tap harmonic component to toggle On or Off
swipe up or down to set amplitude of each harmonic component, swipe faster for rapid adjustment , swipe slower for fine settting
press & hold harmonic component to reset to previous amplitude
change fundamental frequency with pinch in or out
tap Time Domain display to toggle channel 1 On or Off
pinch Time Domain display to change oscilloscope timebase
swipe left/right to set horizontal position of oscilloscope display
