<div class="detailed-solution">
<p>Explanation</p>
<p>A voltage divider that evenly divides the input voltage can be formed with two identically valued resistors, with the sampled voltage taken in between the two.</p>
<p><img src="/c4x/edX/edX101/asset/images_voltage_divider.png"/></p>
<p>A simple high-pass filter without any further constaints can be formed by simply putting a resister in series with a capacitor. The actual values of the components do not really matter in order to meet the constraints of the problem.</p>

When you create a math expression input problem in Studio, you'll use `MathJax <http://www.mathjax.org>`_ to change your plain text into "beautiful math." For more information about how to use MathJax in Studio, see :ref:`MathJax in Studio`.

**Notes for Students**
When you answer a math expression input problem, follow these guidelines.
* Use standard arithmetic operation symbols.
* Indicate multiplication explicitly by using an asterisk (*).
* Use a caret (^) to raise to a power.
* Use an underscore (_) to indicate a subscript.
* Use parentheses to specify the order of operations.
