Acarrier s(t) = 100 cos (2 × 109t) of an fm transmitter is modulated with a tone signal. for thistransmitter, a 1-v (rms) tone produces a deviation of 30 khz. determine the amplitude andfrequency of all fm signal components (spectral lines) that are greater than 1% of the unmodulatedcarrier amplitude if the modulating signal is m(t) = 2.5 cos (3 × 104t).

What’s #16 asking and how do i solve it?

Frequency of electromagnetic waves that a radio station is assigned is called

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
