Generates an array containing an impulse pattern.

	reset determines whether to generate an impulse pattern from initial conditions. If reset is TRUE, the impulse pattern repeats the initial frame. The default is FALSE.
	amplitude is the amplitude of impulse pattern. The default is 1.0.
	delay is the index within impulse pattern at which the impulse occurs. delay must be greater than or equal to 0. If delay is less than 0, the VI sets impulse pattern to 0.
	#s is the number of samples in the waveform. The default is 128.
	impulse pattern returns an array containing the impulse. The largest impulse pattern the VI can generate depends on the amount of memory on the DSP target.

EMB Impulse Generator Details

If the sequence X represents impulse pattern, this VI generates the pattern according to the following equation.

for i = 0, 1, 2, …, n – 1,

where A is the amplitude, d is the delay, and n is total #s.

If delay is greater than #s, the impulse continues in a subsequent frame.
