Stepped Sine

Description#

The signal generator block Stepped Sine can generate logarithmic or linear types of stepped sine 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 stepped sine.

Name#

Name specifies the name of the block.

Sample rate#

Sample rate is the sample rate of the stepped sine.

Start#

Start specifies when the stepped sine 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 stepped sine from start in either s, ms or samples.

Amplitude#

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

Number of steps#

Number of steps is the number of steps the stepped sine should have from start frequency to stop frequency.

Type#

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

Start Frequency#

Start frequency is the frequency where the stepped sine starts.

Stop Frequency#

Stop frequency is the frequency where the stepped sine stops.

Outputs#

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