Design (the frequency response of) the bandpass filter to obtain the modulated signal so that there is less than 1.5 dB of tolerance in the passband and more than 45 dB in the passband attenuation. First determine the cutoff frequency and the order filter.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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?

How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?
