Frequency modulation - Wikipedia, the free encyclopedia (927 words) |
 | Frequency modulation (FM) is a form of modulation which represents information as variations in the instantaneous frequency of a carrier wave. |
| In this equation, f(t) is the instantaneous frequency of the oscillator and f |
| Note that frequency modulation can be regarded as a special case of phase modulation where the carrier phase modulation is the time integral of the FM modulating signal. |
| Frequency Hearing Ranges in Dogs and Other Species (702 words) |
| Reporting the frequency range for hearing in dogs and other species is not a straightforward task - the "how" of determining hearing frequency ranges must first be explained. |
| Frequency is displayed on a logarithmic scale from 10 Hz to 100,000 Hz (100 kHz), while stimulus intensity is displayed (in dB sound pressure level) from -30 to 80 dB. |
