sech(duration, amp, sigma, name=None, zero_ends=True)

Generates unnormalized sech Waveform.

For \(A=\) amp and \(\sigma=\) sigma, applies the midpoint sampling strategy to generate a discrete pulse sampled from the continuous function:

\[f(x) = A\text{sech}\left(\frac{x-\mu}{\sigma} \right)\]

with the center \(\mu=\) duration/2.

If zero_ends==True, each output sample \(y\) is modified according to:

\[y \mapsto A\frac{y-y^*}{A-y^*},\]

where \(y^*\) is the value of the endpoint samples. This sets the endpoints to \(0\) while preserving the amplitude at the center. If \(A=y^*\), \(y\) is set to \(1\). By default, the endpoints are at x = -1, x = duration + 1.

প্যারামিটার

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

• amp (complex) -- Pulse amplitude at duration/2.

• sigma (float) -- Width (standard deviation) of pulse.

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

• zero_ends (bool) -- If True, zero ends at x = -1, x = duration + 1, but rescale to preserve amp.
