Suppose we have a noisy signal (superposition of many frequencies), but
we are only concerned with a particular part of the signal within the noise at a frequency
f(desired) = 1 GHz. In a sentence or two, explain how you could isolate the desired part
of the signal by using low-pass and high-pass filters. Assuming the noise is far from the desired signal in frequency (≥ ±200 MHz from f(desired)), suggest component values that should achieve this effect.
cutoff frequency: w = (RC)^-1
The Attempt at a Solution
If I use the high-pass filter, all lower frequencies will be blocked; if I use the low-pass, all higher frequencies will be blocked. If I use a combo of both in the same circuit with the same R,C values, then wouldn't all frequencies be blocked?
