De-emphasis is: decreasing the relative strength of low-frequency components of the output signal of an FM detector of an FM receiver. increasing the relative strength of high frequency components before being fed into the modulator of an FM transmitter. increasing the relative strength of low-frequency components before being fed into the modulator of an FM transmitter. decreasing the relative strength of high-frequency components of the output signal of an FM detector in an FM receiver.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
