# qiskit.pulse.library.sawtooth¶

sawtooth(duration, amp, freq=None, phase=0, name=None)[fuente]

Generates sawtooth wave Waveform.

For $$A=$$ amp, $$T=$$ period, and $$\phi=$$ phase, applies the midpoint sampling strategy to generate a discrete pulse sampled from the continuous function:

$f(x) = 2 A \left( g(x) - \left\lfloor \frac{1}{2} + g(x) \right\rfloor\right)$

where $$g(x) = x/T + \phi/\pi$$.

Parámetros
• duration (int) – Duration of pulse. Must be greater than zero.

• amp (complex) – Pulse amplitude. Wave range is $$[-$$ amp $$,$$ amp $$]$$.

• freq (Optional[float]) – Pulse frequency, units of 1./dt. If None defaults to 1./duration.

• phase (float) – Pulse phase.

• name (Optional[str]) – Name of pulse.

Ejemplo

import matplotlib.pyplot as plt
from qiskit.pulse.library import sawtooth
import numpy as np

duration = 100
amp = 1
freq = 1 / duration
sawtooth_wave = np.real(sawtooth(duration, amp, freq).samples)
plt.plot(range(duration), sawtooth_wave)
plt.show()
