Time scaling: Compression of a signal in time domain is equivalent to expansion in frequency domain and vice versa. Proof: Proof: Y ( ω) = ∫ − ∞ ∞ y ( t) e − j ω t d τ. Y ( ω) = ∫ − ∞ ∞ x ( a t) e − j ω t d τ. Put at = τ then t = τa ∴dt = 1a dτ and limits will remain same. fast home internet service providers
