qiskit.pulse.library.cos

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

Generates cosine wave Waveform.

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

Parameters

• duration (int) – Duration of pulse. Must be greater than zero.
• amp (complex) – Pulse amplitude.
• freq (Optional[float]) – Pulse frequency, units of 1/dt. If None defaults to single cycle.
• phase (float) – Pulse phase.
• name (Optional[str]) – Name of pulse.

Return type

Waveform
