Q1:

Consider the resonant circuit as shown below

The circuit is scaled modified so that Zmax 104 and ωo = 108 Radians. Find the required element values

A R = 104 L = 5 μH C = 20 pF

B 1000 L = 50 μH C = 200 pF

C 10 K L = 50 μH C =20 pF

D None of these

ANS:C - 10 K L = 50 μH C =20 pF

Impedance scaling factor kx As = 10 Radians New value for elements are R' = kzR = 1000 x 10 = 10 kΩ .
