### cos

**Block Inputs:** fx1.16 or fx1.32 format.

The cos block produces the cosine of the input signal in
scaled fixed-point notation. The block automatically uses fx1.16 or fx1.32 based
on the data type of the input signal. The input signal is represented in “per
unit” angles. This means the angle input is implicitly multiplied by 2π so that
a value sweeping from zero to one will produce a complete cycle of sin output.
Typically, this block is fed by a repeating fixed-point ramp that runs from zero
to one.
