Problem 56-2.
Source: Problem elaborated by the author of the site.
We wish to use an LC parallel circuit, show in Figure 56-2.1, to tune the frequencies corresponding to the
AM range, which ranges from 530 KHz to 1600 KHz. Using an inductor
of 100 µH calculate the value of a variable capacitor, which associated
in parallel with a fixed value, provides the AM band tuning.
