Chirp

Description#

The signal generator block chirp can generate logarithmic or linear types of chirps based on a start and stop frequency. This is a great stimuli to use with SAFEs loudspeaker response tool.

Mx1

Output#

The output is a single dimension Mx1 chirp.

Name#

Name specifies the name of the block.

Sample rate#

Sample rate is the sample rate of the chirp.

Start#

Start specifies when the chirp should start. If start is above 0 s the start is zeropadded accordingly. The start can be defined in either s, ms or samples.

Length#

Length specifies the length of the chirp from start in either s, ms or samples.

Amplitude#

Amplitude is the amplitude (Peak) of the chirp. As the signal is generated on the computer the unit is defined as FS.

Type#

Type is the chirp type. It can either be logarithmic or linear.

Start Frequency#

Start frequency is the frequency where the chirp starts.

Stop Frequency#

Stop frequency is the frequency where the chirp stops.

Outputs#

Outputs specifies the number of output(s) the block will have. Each output will output the same chirp.
