CosineRise

class iqm.pulse.playlist.waveforms.CosineRise(n_samples)

Bases: Waveform

Cosine Rise waveform.

This waveform assumes that during its duration, the only thing happening is signal occurring to the required amplitude. The waveform is made for pairing with ‘Constant’ waveform to enable arbitrarily long pulses with smooth rise part. The rise time is equal to pulse duration.

Parameters:

• rise_time – Dummy parameter, used only as due to a bug. FIXME it is not used, placed for resolving exa bug

• n_samples (int) –

Module: iqm.pulse.playlist.waveforms

Attributes

n_samples

Requested number of samples for the waveform.

Methods

_sample(sample_coords)

Actually samples the waveform.

Parameters:

sample_coords (ndarray) – coordinates of the samples to be returned

Returns:

array of samples (same shape as sample_coords, dtype == float)

Return type:

ndarray
