Requires: MathScript RT Module


y = pam(x, m)

y = pam(x, m, phi)

y = pam(x, m, phi, type)

Legacy Name: pammod


Modulates a sequence of integers into a series of Pulse Amplitude Modulated (PAM) symbols.



Name Description
x Specifies the sequence of integers to modulate. x is an I32 scalar, vector, or matrix in the range of [0, m-1].
m Specifies to use m-ary PAM modulation. m should be an integer equal to or greater than 2.
phi Specifies the initial phase in radians. The default phi is 0.
type Specifies the method to map the integers to modulated symbols. type is a string that accepts the following values:

'Bin' (default) Uses binary mapping to the modulated symbols.
'Gray' Uses Gray-coded mapping to the modulated symbols.


Name Description
y Returns the modulated symbols. y is a complex, double-precision, floating-point scalar, vector, or matrix.


The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine Yes
Supported on RT targets Yes
Suitable for bounded execution times on RT Not characterized


X = randint(1, 1000, 8)
Y = pam(X, 8, 0, 'Gray')
