## Homework Statement

For the circuit in the picture below, with [itex]V_{c}(t=0) = 0[/itex] and a voltage source with period T described by

[tex]V_s(t) = \sum_{-\infty}^\infty (-1)^{n}g(t-nT)[/tex]

where

[tex]g(t) = 7[u(t)-u(t-T)]\quad [Volt][/tex]

and [itex]u(t)[/itex] is a step function described by

[tex]

u(t) =

\begin{cases}

1 & \text{if } t \geq 0 \\

0 & \text{if } t < 0

\end{cases}

[/tex]

What is the maximal voltages across the capacitor?

What is the maximal voltages across the resistor?

## Homework Equations

## The Attempt at a Solution

The voltage source is a pulse train with amplitude [itex]\pm 14 \quad [Volts][/itex] and since at time [itex]t = 0[/itex] we may consider the cap. as a short-circuit, we have [itex]V_{R}(t=0) = 14 \quad [Volts]. [/itex]

I'm having trouble figuring out what the maximal voltage across the cap. is.

Should I apply transient analysis?

Thanx.
