FM stands for frequency modulation. The definition is: when the frequency of the carrier wave is changed in accordance with the intensity of the signal, it is called frequency modulation. In frequency modulation, only the frequency of the carrier wave is changed in accordance with the signal. However, the amplitude of the carrier wave remains unchanged.
Arousal can either enhance or hinder concentration, depending on the individual and the situation. In some cases, moderate arousal can improve focus and alertness, leading to better concentration. However, high levels of arousal, such as stress or anxiety, can overwhelm the brain's capacity to concentrate, resulting in decreased focus and performance.
The scientific and medical definition of 'arousal' or being 'aroused' simply refers to someone who is awake and paying sharp attention. In more casual use, arousal is almost exclusively used to refer to the reproductive system.
1)antenna scanning modulation is time oriented 2)internal modulation of clutter3)system instability
The vocal cords, also known as the vocal folds, are the section of the larynx that affects voice modulation. When air passes through the vocal cords, the tension and positioning of the cords can be adjusted to produce different pitches and tones, allowing for modulation of the voice.
AM - Amplitude Modulation FM - Frequency Modulation
modulation
Frequency Modulation and Phase Modulation
frequency modulation..
due to velocity modulation density modulation occurs in TWT
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
the modulation system is of FM
i dont know ans. of this.
Frequency modulation Phase modulation
QAM is a combination of phase modulation & amplitude modulation.
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
