Web1. Let us define the function. f ( τ) = u ( τ) − u ( τ − 4) = { 1 0 < τ < 4 0 τ < 0 or τ > 4. (One way of seeing the second equality is that u ( τ) is zero for τ < 0 and one for t > 0, and u ( τ − 4) is zero for τ < 4 and one for τ > 4. Thus subtracting them, u ( τ) − u ( τ − 4) becomes what I wrote above.) This means ... WebThe unit impulse function or Dirac delta function, denoted δ ( t ), is usually taken to mean a rectangular pulse of unit area, and in the limit the width of the pulse tends to zero whilst … WebImpulse Signal. The incoming impulse signal from each synapse to the neuron is either excitatory or inhibitory, which means helping or hindering firing. From: Knowledge Is … team work message gif
