 * Introduction
 the Heaviside Step Function $H(t)$ is an important function in signal analysis. It is defined as follows:
 \begin{align}
-\label{}
-H(t) =
-\[   \left\{
+H(t) = 
+\left\{
 \begin{array}{ll}
 0 & t \leq 0 \\
 1 & t > 0
 \end{array}
-\right. \]
+\right.
 \end{align}
 and it is related to the [[id:90574fea-88f4-4b80-9cda-32cff0bcb76d][dirac delta]] distribution by taking a [[id:31d3944a-cddc-496c-89a3-67a56e821de3][derivative]]:
 \begin{align}
-\label{}
-\frac{dH}{dt} = \delta(t)
+\delta(t) = \frac{dH}{dt}
 \end{align}
 Note that this definition of the derivative may be different than that of the regular derivative definition.
