1. Sketch cos(ω 1 t) sin(ω 2 t) when ω 1 ≫ ω 2 . What changes if ω 1 ≪ ω 2 ? What happens if ω 1 and ω 2 are close in value? 2. Define x(t) = Π(t/3) + Λ(t/4). Sketch over a suitable range of t. 3....

1. Sketch cos(ω₁t) sin(ω₂t) when ω₁
≫ ω₂. What changes if ω₁
≪ ω₂? What happens if ω₁
and ω₂
are close in value?

2. Define x(t) = Π(t/3) + Λ(t/4). Sketch
over a suitable range of t.
