Chirp Signal
A sinusoid with a linearly varying frequency.
Description
The Chirp Signal block generates a sinusoidal signal whose frequency varies linearly with time. You can use this block for spectral analysis of nonlinear systems. The block generates a scalar or vector output.
The Initial frequency, Target time, and Frequency at target time parameters define the output of the block. You can specify any (or all) of these variables as scalars or arrays. All parameters specified as arrays must have the same dimensionality. The block expands scalar parameters to have the same dimensionality as parameters as arrays. The output of the block has the same dimensionality as the parameters.
Parameters
Initial frequency - initial frequency (Hz)
0.1 (by default)
| scalar
| vector
| matrix
The initial frequency of the signal as a scalar, vector, matrix or ND array.

Value |
|
By default |
|
Target time - Target time (seconds)
100 (by default)
| scalar
| vector
| matrix
The time in seconds for the frequency to reach the Frequency at target time. Target time can be specified as a scalar, vector or matrix. Once the target time is reached, the frequency continues to change at the same rate.

1 (by default)
| scalar
| vector
| matrix
Frequency (in hertz) of the signal at the target time as a scalar, vector, matrix or ND array.
