The asynchronous heterodyne detection is _________ more sensitive than the dual filter direct detection FSK receiver.

The asynchronous heterodyne detection is _________ more sensitive than the dual filter direct detection FSK receiver. Correct Answer 0.40 dB

The orthogonal polarization leads to the amplified noise structures and behavior in the FSK receiver. This leads to the loss in the sensitivity and accuracy of the FSK receiver.

ASK with heterodyne detection can achieve same SNR limit as ASK with asynchronous detection.
A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
