Let us assume a solution i(t=Ae, where a and S, are constant to be determined

We define the unit-step forcing function as a function which is zero for all values of argument which are less than zero and which is unity(1) for all positive values of its argument

4-5 Simple capacitor-OP-AMP-circuits Integrator op-amp circuit (Integrator):

Two circuits are dual if the mesh equations that characterize one of them have the same mathematical form as nodal equations that characterize the other

The inductance which is equivalent to several inductance connected in series is simply the sum of the series inductance

The displacement current flowing internally between the capacitor plates is exactly equal to the conduction current flowing in the capacitor leads

A current-carrying conductor produced a magnetic field (1800). A changing magnetic field could induce a voltage in a neighboring circuit(1820)

Let=R3 and The result we have found for two /R =k, we have inputs may be extended to any v2=-k(v1+3) number of inputs

The voltage follower is a circuit in which the output is identical to the input

UB =A(DA-UB) =cons tant The inverting OP-AMP circuit
