Someone please help.
A radio needs to be tuned to a range of values between 526.5 -
1606.5 kHz. Choose a combination of inductor and variable
capacitor values within a tuned circuit that would meet this
requirement. Choose practical components from standard vendor
web sites (e.g. Maplin/RS) if possible and provide full item
description.
Let L = 100 uh.
Xl = 6.28*526.5*10^3*100*10^-6 =
330.642 Ohms = Xc.
C = 1/6.28*F*Xc = 1/6.28*526.5*10^3*330.642 = 0.00091 uF = 910 pF. at 526.5 kHz
Xl = 6.28*1606.5^10^3*100*10^-6 = 1,009.4 Ohms = Xc.
C = 1/(6.28*1606.5*10^3*100*10^-6) = 9.9*10^-4 uF = 990 pF.
C = 910 pF to 990 pF.
Choose closest standard values.
