The signal generator block
sweep can generate logarithmic or linear types of sweeps. The sweeps are designed in
the frequency domain according to Transfer-Function Measurements with Sweeps
by Müller and Massarani.
The output is a single dimension
|Sample rate||48000 Hz|
|Start Sweep||50 Hz|
|Stop Sweep||16000 Hz|
Name specifies the name of the block.
Sample rate is the sample rate of the sweep.
Start specifies when the sweep should start. If start is above 0 s the start is zeropadded accordingly.
The start can be defined in either
Length specifies the length of the sweep from start in either
Amplitude is the amplitude (Peak) of the sweep. As the signal is generated on the computer the unit is
Type is the sweep type. It can either be
Phase-in is the sweeps starting frequency. The sweep will not be white or pink in the frequency domain, dependent on type, at this frequency.
Start frequency is the frequency where the sweep starts being white or pink in the frequency domain.
Stop frequency is the frequency where the sweeps stop being white or pink in the frequency domain.
Phase out is the sweeps stopping frequency.
Outputs specifies the number of output(s) the block will have. Each output will output the same sweep.
A logarithmic sweep with default attributes
A logaritmic sweep in frequency domain with default attributes and 48000 point FFT. Because the sweep is designed in the frequency domain the sweep is very smooth without spikes.
