Cosine Icon

`Cosine`

Generate Cosine signal.

This component extends from Signal

Usage

Cosine(start_time=0.0, offset=0.0, amplitude, frequency, phase)

Parameters:

Name	Units	Default value
`start_time`	s	0
`offset`	–	0
`amplitude`	–
`frequency`	Hz
`phase`	rad

Connectors

y - This connector represents a real signal as an output from a component (RealOutput)

\[ \begin{align} y\left( t \right) &= ifelse\left( \mathtt{start\_time} < t, \mathtt{offset} + \mathtt{amplitude} \cos\left( \mathtt{phase} + 6.2832 \mathtt{frequency} \left( - \mathtt{start\_time} + t \right) \right), \mathtt{offset} \right) \end{align} \]
