3Square Root IQN
Purpose Calculate the square root or inverse square root
Library tiiqmathlib in Embedded Target for TI C2000 DSP
Description This block calculates the square root or inverse square root of an IQ number
and returns an IQ number of the same Q format. The block uses table lookup
and a Newton-Raphson approximation.
Function option — Whether to calculate the square root or inverse square root
•
Square root (_sqrt) — Compute the square root
•
Inverse square root (_isqrt) — Compute the inverse square root
