What is unit sample function?
The unit sample function, often referred to as the unit impulse or delta function, is the function that defines the idea of a unit impulse in discrete time.
What is a unit sample sequence?
Unit Sample sequence or Impulse sequence is defined as δ[n]=1,n=0,0,n≠0. and they are related via the sum relation by u[n]=∞∑k=−∞δ[k].
What is a unit sample signal?
The unit impulse sequence is a sequence of discrete samples having unit magnitude at origin and zero magnitude at all other sample instants. The figure given below depicts the unit of impulse sequence. It is defined as, The discrete-time version of the unit impulse is defined by. δ [ n ] = 1 , n = 0 0 , n ≠ 0.
