At a particular frequency ω, the amplitude of the input signal frequency spectrum is 20 dB. The bode plot of your filter at the same frequency ω is − 10 dB. If you were to measure the amplitude of the output signal frequency spectrum at ω, what would the value be? Give your answer in dB, and omit units from your answer.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
