A carrier signal with a frequency of 100 MHz, frequency by band limited information sign with 2 KHz modulating. Maximum frequency deviation of the FM sign (Kf) 25 KHz and information sign amplitude (Am) If it is 15.7 Volts; a) Calculate the bandwidth of the FM signal?

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
