a) Select the correct statement regarding the difference between the FM and the AM modulated signal waveforms. AM modulation FM modulation -4 -2 -6 -3 3 2 3 time x10-3 time x103 combined message and AM signal combined message and FM signal 5 -1 -2 -4 -5 -3 -6 1 1 2 3 time x10-3 time x103 a. There is no difference between the FM and AM signal waves because they are both modulated by the same message wave, m(t) = Amcos(2nfmt) b. The AM modulated signal accurately represents the message; the FM modulated signal does not accurately represent the message wave c. Neither AM nor FM modulated signals accurately represents the message wave d. The AM modulated signal accurately represents the message; the FM modulated signal accurately represents the message wave amplitude amplitude amplitude

All of the following statements about the TRIAC could be true except: O A. TRIACs are not used in automotive applications O B. None of the other choices are correct OC. TRIACS are not suitable for high frequency (over 100k) switching applications O D. TRIACS are largely used for power application at the line frequency O E. TRIACS cannot be used in household appliances

please show work. i will give your work a thumbs up 7. Consider the oscilloscope screen shot below: ek Run 4.00p 1.0000 Vpp 0.000000 1. 5.000S/ IM points 500mV AFG Sine 100.00 Hz 0.00 V As shown the Volt / Div - 500mV per division, Time Base - 4.00 us per division, and Frequency is 100 KHz: a) Determine the peak-to-peak voltage (Vpp) and half-cycle average voltage (Vave). b) Determine the peak-voltage (Vpk) and root-mean-square voltage (Vrms). c) What is the period (T) of the IMHZ signal?

Just you EDIT e. Figure 1 shows the waveform of an amplitude-modulated signal as displayed on an oscilloscope. Both the carrier and the message signal are sinusoidal. Find the modulation index and the power efficiency of the amplitude-modulated signal. -1- More Add to story
