A mass m suspended from an ideal spring with spring constant k oscillates up and down with very small amplitude and period T. If the amplitude of the oscillation is doubled, how will the period change? The period would double. The period would be reduced by half. none of these The period would be reduced by a factor of 4. The period would be reduced by a factor of root 2. The period would be increased by a factor of root 2. The period would not change.

Question #1): An engineer has designed a circuit with the transfer function illustrated below. (H(f) is real.) I H(f) 1 -d d f Hz The input to the circuit is a random telegraph signal X(t) = \pm a (volts) changing sign every c seconds on the average. (So c is not the arrival rate; see previous problem.) What is the (total) power in the output? Call it M(12). Codes: A= 1 B=7 C= 3 D= 4 E= 4 F= 0
