Signal Transformation Playground

Explore how the sign s, scale a, and bias b in x(s·a·t + b) shape a signal. Adjust the controls to see each intermediate step.

s = +1
a = 1.0
b = 0.0
x(t)

Step 0 — Original

Starting point using the base function.

x(t)

Step 1 — Mirror

Apply the sign: t → s·t.

x(t)

Step 2 — Scale

Stretch or compress time: t → a·t.

x(t)

Step 3 — Shift

Add the bias: t → t + b.
