qiskit.pulse.library.square

square(duration, amp, freq=None, phase=0, name=None)

Generates square 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:

\[f(x) = A \text{sign}\left[ \sin\left(\frac{2 \pi x}{T} + 2\phi\right) \right]\]

with the convention \(\text{sign}(0) = 1\).

Parameter

• 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.
