SIGNALS AND SYSTEMS

• 1.      All the signals are basically Vectors
• 2.      A vector can be represented in terms of its co-ordinates
• 3.      A signal is said to be periodic if it repeats at regular intervals
• 4.      The condition for periodicity of continuous time signal is x(t)=x(t+T₀)
• 5.      Trigonometric Fourier series can be represented in Compact Form
• 6.      Single Valued Property must have only one value at any time instant within time interval T₀
