Signal

class Signal(envelope=0.0, frequency=0.0)

A real-valued harmonic signal.

Parameters:

• envelope (complex | Callable[[float], complex] | Callable[[ndarray | Array], ndarray | Array]) – Constant value or callable function.

• frequency (float) – Frequency of the signal.

Note

The signal is the real part of a complex exponential:

\[s(t) = \Re\{A(t)e^{i 2 \pi f t}\},\]

where \(A(t)\) is represented by the envelope, \(f\) represented by the frequency, and \(t\) is the time.

Attributes

envelope	a constant or a callable of time (in \(\text{T}\)).
frequency	Carrier frequency of the signal (in \(\text{MHz}\)).
