Heaviside Step Function: Also denoted as

The Heaviside step function can also be denoted:

  • $\map {H_c} t$
  • $\map {\theta_c} t$

Variants of the letter $u$ can be found:

  • $\map {\UU_c} t$
  • $\map {\operatorname u_c} t$

Some sources bypass the need to use a subscript, and present it as:

$\map {\UU} {t - c} = \begin {cases} 1 & : t > c \\ 0 & : t < c \end {cases}$
