Description
This block generates a variable frequency sinewave. Initial frequency and its variation across time (Increase rate) are specified as block parameters.
The frequency is changing linearly starting from Initial frequency and increases with the Increase rate.If we denote F the Initial frequency and R the Increase rate, the output of the block is computed as follows:Sin(2*PI*(F+R*time/2)*time)
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
FInit | Initial frequency | Initial Frequency of the sine wave. Can be a scalar (one signal) or a vector (multiple signals are generated). | Matrix | |
IncreaseRate | Increase rate | Variation rate (can be either positive or negative) of the sine wave. If scalar, applies to all signals. If a vector, applies to each signal vector - provided size matches the size of the Initial frequency vector. | Matrix |
