Trig Fcn IQN

3-65

3Trig Fcn IQN

Purpose Calculate the sine, cosine, or arc tangent

Library tiiqmathlib in Embedded Target for TI C2000 DSP

Description This block calculates basic trigonometric functions and returns the result as an

IQ number. Valid Q values for

IQsin and IQcos are 1 to 29. For all others, valid

Q values are 1 to 30.

Function option — Type of trigonometric function to calculate.

•

_IQsin — Compute the sine (sin(A)), where A is in radians.

•

_IQsinPU — Compute the sine per unit (sin(2*pi*A)), where A is in

per-unit radians.

•

_IQcos — Compute the cosine (cos(A)), where A is in radians.

•

_IQcosPU — Compute the cosine per unit (cos(2*pi*A)), where A is in

per-unit radians.

•

_IQatan — Compute the arc tangent (tan(A)), where A is in radians.
