Avoltage source with a Thvenin resistance of 50 has a spurious (undesirable) conducted emission at 25 krad=s.

Avoltage source with a Thévenin resistance of 50 Ωhas a spurious (undesirable) conducted emission at 25 krad=s. Connecting an inductor and capacitor in series across the 50-Ω source produces a bandstop filter that can eliminate the troublesome signal.

To avoid reducing nearby useful signals, the stopband bandwidth must be less than 1 krad/s. Select values of L and C. Use Multisim to simulate the design and validate the center frequency, the bandwidth, and the depth of the notch in decibels.
