Description
Block MFSK Waveform Generates a continuous multi-position frequency modulation (MFSK) signal with a preset time step. , frequency deviation , by frequency offset and the number of steps . The signal at the output of the block is an integer and is determined by the number of samples, the number of time steps. , the number of frequency deviation steps (Fig.1):
Ports
Output
Port_1 is a continuous radiation signal with multi—position frequency modulation
complex column vector
The output of the block is specified as a complex column vector containing signal samples. The number of samples in the signal depends on the following parameters:
-
If the Output signal format parameter is set to
Steps, then the output of the block is determined by the parameter Number of frequency steps in output or the number of steps . -
If the Output signal format parameter is set to
Samples, the output of the block is determined by the Number of samples in output parameter or the number of samples. -
If the Output signal format parameter is set to
Sweeps, the output of the block is determined by the Number of sweeps in output parameter or the number of frequency deviation steps. .
Parameters
Sample time - interval between calculation steps
−1 (by default) | скаляр
Specify the parameter Sample time as a non-negative number. To inherit the discrete step of the system, set the value of this parameter to −1.
