DescriptionFourierSynth 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 componentsFundamental frequency adjustable from 50Hz to 1kHzIndividually control amplitude and On/Off state of each harmonicDC term available on iPad displaySelect from a range of 10 preset waveforms  Square, Triangle, Sawtooth, Amplitude Modulation, Impulse, Half and Full Wave RectificationMonitor waveforms externally on an Oscilloscope or Listen to audio outputChoose which sinusoid or ‘sum‘ appear on display or audio output Listen to musical chords and hear the effects of phase change on their soundUse the full range of Swipe, Tap, Pinch, Tap&Hold; Gestures tap harmonic component to toggle On or Offswipe up or down to set amplitude of each harmonic component,  swipe faster for rapid adjustment , swipe slower for fine setttingpress & hold harmonic component to reset to previous amplitudechange fundamental frequency with pinch in or outtap Time Domain display to toggle channel 1 On or Offpinch Time Domain display to change oscilloscope timebaseswipe left/right to set horizontal position of oscilloscope display
