BITSCALE

Purpose:

Converts raw AD counts to scaled engineering values.

BITSCALE(xi, numbits, yl, yh)

xi	-	An input series or scalar.
numbits	-	An integer. The number of AD converter bits.
yl	-	A real. The low value output range.
yh	-	A real. The high value output range.

A series or real.

bitscale(4096, 16, -2.5, 2.5)

returns 0.312543, the corresponding output for input 4096 of a 16 bit converter with an output range of +-2.5

bitscale(-128..127, 8, 0.0, 10.0)

returns a series ranging from 0.0 to 10.0

BITSCALE assumes offset binary input data, i.e the input data ranges from:

-(2^numbits)/2 to (2^numbits)/2 - 1.

BITSCALE does not automatically clip out of range values.
