How do we manipulate the Amplitude (Y-axis) of a signal? 🎚️
In this video on Engineering Logic, we cover the basic arithmetic operations on signals:
1. *Amplitude Scaling:* $y(t) = A \cdot x(t)$.
2. *Signal Addition:* $y(t) = x_1(t) + x_2(t)$. (Point-by-point addition).
3. *Signal Multiplication:* $y(t) = x_1(t) \cdot x_2(t)$. (Windowing/Modulation).
We solve a graphical problem: *"Draw $y(t) = 2x(t) - 1$"* to show how scaling and DC shifting work together.
