Python SawtoothSignal.make_wave Examples

Example #1

File: chap2_test.py Project: musiclvme/debug_thinkdsp

def test_Sawtooth():
    signal = SawtoothSignal(200)
    duration = signal.period * 3
    segment = signal.make_wave(duration, framerate=10000)
    segment.plot()
    decorate(xlabel='Time (s)')

    wave = signal.make_wave(duration=0.5, framerate=10000)
    wave.apodize()
    spectrum = wave.make_spectrum()
    spectrum.plot()
    decorate(xlabel='Frequency (Hz)')
