Final answer:
Frequency modulation (FM) utilizes frequency modulation of the transmitted pulse to improve signal-to-noise ratio.
Step-by-step explanation:
The technique that utilizes frequency modulation (FM) of the transmitted pulse to improve signal-to-noise ratio is Frequency modulation.
Frequency modulation (FM) is a method of placing information on electromagnetic waves by modulating the frequency of a carrier wave with an audio signal. In FM radio, the frequency of the carrier wave is modulated by the audio signal without changing its amplitude, resulting in a wave of constant amplitude but varying frequency. This technique helps improve the signal-to-noise ratio, resulting in clearer audio transmission.
For example, FM radio stations use frequency modulation to transmit a higher quality audio signal compared to AM radio stations that use amplitude modulation. By modulating the carrier wave's frequency, FM radio reduces noise interference and delivers a more accurate representation of the original audio signal.
