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.
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.
