## PHYS345 Electricity and Electronics

**Answer for E8-1**
The result of rationalizing Eq.1 is:

**G**_{v} = G_{0}(1-*j*x)/(1+x^{2})
where x = f/f_{u} has been introduced as a dimensionless frequency.

This expression is now in standard form and the phase angle may be extracted from the
imaginary and real parts:

tan(phase angle) = *Im*{**G**_{v}}/*Re*{**G**_{v}} = -x.

Find the phase angle for x = 0.5, 1.5, 2.5, and infinity.
