The duty cycle of a pulse width modulated (PWM) signal is changed according to a table of sine values.
Using the MATLAB code that they used, we generated a table of sine values and stored it into flash memory.
In order to mimic the "pluck" sound and then resonate for a moment, we modulate the amplitude of the sine values to grow rapidly and then slowly die out.
Starting from the non-rotation invariant uniform LBP (called nriLBP), the pattern is described by the cosine and sine values of the angular portion defined by the '1's.
Alternatively, the NCO can contain only one LUT for storing the sine values and use a 90° phase offset (accessing the LUT with a sample offset) to generate the cosine values.

The proposed tracker eliminates the use of the current sensor by using only the voltage sensor: The current sensor is substituted with a new quantity, which is the sine value of the power-angle (the phase angle between the inverter output voltage and the power grid voltage).
For the 5R parallel manipulator, the ETI value equals the sine value of the angle between f 1 and f 2 vectors (l 12 and l 22 vectors).
The sine value of the transmission angle is adopted to develop a global force transmission index, and has been applied to performance analysis of the planar 5R parallel manipulator [28].
Read down the Sine column until you find the value "0.5" and then look at the angle measure corresponding to that sine value.
With a calculator with trig function capability, you input the sine value (if you didn't already divide the opposite by the hypotenuse with the calculator to find it) and then press the appropriate key or keys.
The hypotenuse is always 1, as that is the radius of the circle, and since any number divided by 1 is itself, and the opposite side equals the y-value, it follows that the sine value is the y-coordinate of the point.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
