(b) What are the values of the carrier frequency and the modulation frequency? (c) What is the value of the modulation index? (d) What is the transmission efficiency (ratio of modulated to total power) in this example? (e) Sketch the spectrum of this modulated waveform indicating the relative magnitudes of the various spectral components. (f) The modulating wave in this example is substituted with a square wave of 50% duty cycle and of fundamental frequency 1.0 MHz. Sketch the absolute value of the spec- trum of the modulated waveform indicating the frequencies and relative magnitudes of the sideband components. (g) Demodulation of this type of signal is usually accomplished…

(G. F. Franklin, J. D. Powell and A. E. Naeini, Feedback Control of Dynamic Systems, 6th Edition, Prentice Hall, 2010). "A measure of the degree of instability in an unstable aircraft response is the amount of time it takes for the amplitude of the time response to double (see the following figure) given some nonzero initial condition."
