DynamicSystems[Sinc] - generate a sinc pulse

Calling Sequence

Sinc( )

Sinc(yht, Tw, t0, y0, opts)

Parameters

yht

-

(optional) algebraic; height of main pulse above baseline; default is 1

Tw

-

(optional) algebraic; half-width of main pulse; default is 1

t0

-

(optional) algebraic; delay to main pulse; default is 0

y0

-

(optional) algebraic; baseline; default is 0

opts

-

(optional) equation(s) of the form option = value; specify options for the Sinc command

Description

• 

The Sinc command generates a sinc pulse.

• 

By default, Sinc returns an expression representing the waveform. If the option discrete is assigned true, Sinc returns a Vector of data points.

• 

The optional parameter yht specifies the height of the main pulse above the baseline. Its default value is one.

• 

The optional parameter Tw specifies the half-width of the base of the main pulse; this is the duration from t=t0 to the first crossing of y=y0.

• 

The optional parameter t0 specifies the temporal location of the center of the main pulse. Its default value is zero.

• 

The optional parameter y0 specifies the baseline. Its default value is zero.
