👉 A Phillips sine wave is a mathematical function that resembles a sine wave, but with a slight difference in its amplitude and frequency. It's named after the famous electrical engineer Charles Babbage who designed one of his machines to simulate the behavior of the sine wave.
The formula for a Phillips sine wave can be written as:
f = π / 2
sin(π
x)
where f is the frequency, x is the phase shift (or amplitude), and π is approximately equal to 3
