Pattern Generator (Gaussian Monopulse) (G Dataflow)

Version:

Generates a signal containing a Gaussian monopulse.

amplitude

Amplitude of the pattern.

Default: 1

delay

Shifts the pattern in the time axis.

Default: 0

center frequency

Center frequency, or frequency of the carrier, in Hz.

center frequency must be greater than zero.

Default: 1

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

dt

Sampling interval. This input must be greater than zero. If this input is less than or equal to zero, this node sets the output pattern to an empty array and returns an error.

Default: 0.1

samples

Number of samples in the pattern. If this input is less than 1, the node sets the output pattern to an empty array and returns an error.

Default: 128

Gaussian monopulse

Output Gaussian monopulse pattern.

error out

Error information. The node produces this output according to standard error behavior.

Algorithm for Generating the Gaussian Monopulse

If the sequence Y represents Gaussian monopulse, this node generates the pattern according to the following equations:

${y}_{i}=2\pi a\sqrt{e}{x}_{i}{f}_{c}{e}^{-2{\left(\pi {x}_{i}{f}_{c}\right)}^{2}}$

and

${X}_{i}=i*\mathrm{\Delta }t-d$

for i = 0, 1, 2, ..., n - 1

where

• a is the amplitude
• d is the delay
• fc is the center frequency
• n is the number of samples
