WebGiven an FM modulator with a deviation sensitivity K1= 3.7 kHz/V and a modulating signal vm = 5.2 sin(2π1,906t), determine the carrier swing in kHz For an FM modulator with an unmodulated carrier amplitude Vc= 14 V, a modulation index m = 1, and a load resistance RL = 8 ohms, determine the power (in watts) in the modulated carrier The percent … WebJun 13, 2014 at 12:48. 1. Tu sum up Asin (ωt) is a power signal and Ae−λ t is an energy signal. In general infinite non bounded signals are analyzed as power signals because they have infinite energy. Bounded signals are analyzed as energy signals and have 0 power.
WebJan 13, 2024 · A signal x(t) is said to be a power signal if and only if its average power is finite, thus implying that energy is infinite. ...
