WebDefinition 4.3. 1. A random variable X has a uniform distribution on interval [ a, b], write X ∼ uniform [ a, b], if it has pdf given by. f ( x) = { 1 b − a, for a ≤ x ≤ b 0, otherwise. The uniform distribution is also sometimes referred to as the box distribution, since the graph of its pdf looks like a box. See Figure 1 below. WebThe definition of entropy for a continuous signal is: h [ f] = E [ − ln ( f ( X))] = − ∫ − ∞ ∞ f ( x) ln ( f ( x)) d x According to Wikipedia, it can be negative. When would that happen? As far as I understand, f ( x) is always ∈ [ 0, 1] so f ( x) ⋅ l n ( f ( x)) can only be negative. What am I missing ? entropy information-theory Share Cite high power fiber amplifier
