Question
Suppose that a spacecraft near Neptune has measured a quantity A and sent it to earth in the form of a periodic signal A cost of amplitude A. On its way to earth, the signal picks up periodic noise,
containing only second and higher harmonics. Suppose that the signal h(t) actually received on earth is graphed below.
10
-pi
-pi/2
pi/2
pi
-10
Determine the signal that the spacecraft originally sent and hence the value A of the measurement.
A =
-60
