Suppose you are tasked with attenuating a $60$ Hz input component signal by

a factor of $100$ using an RL high$-$pass circuit.

$($a$)$ What is the corner frequencycf $?$ How does this corner frequency relate to the time constant

for an RL circuit? $(3$ points$)$

$($b$)$ You wish to design this circuit, and of course you have on hand a $17$ k$$ resistor for the job.

What is the necessary value of L$?$
