When Sweep Time Is Greater than Target Time

This example shows the unexpected behavior that might arise in the Chirp block when the Sweep time is greater than Target time. The Time Scope displays the signal output, and the Spectrum Analyzer displays the spectrogram in the frequency domain.

Set the Sweep time parameter to 1.5 and specify the final frequency of a bidirectional sweep by setting Target time equal to Sweep time. The sweep reaches the Target frequency (25 Hz) at the Target time (1 second), but since Sweep time is greater than Target time, the sweep continues on its linear path until one Sweep time (1.5 seconds) is traversed.

Unexpected behavior might arise when you set Sweep time greater than Target time.

Run the model to see the chirp signal output and a spectrogram of the frequency domain.
