What type of modulation interprets waves based on oscillating frequency?

Explanation:
Frequency modulation encodes information by changing the carrier’s frequency in response to the input signal. As the input varies, the instantaneous frequency of the carrier speeds up or slows down, while the overall amplitude stays roughly constant. This is different from phase modulation, where the phase of the carrier shifts, and from amplitude modulation, where the height of the waves changes. Pulse modulation uses discrete pulses instead of a continuous sine wave. So interpreting waves based on oscillating frequency is what frequency modulation does.
