1. If any root of characteristic equation has a positive real part the impulse response is unbounded and system is unstable.
2. If all the roots of a characteristic equation have negative real parts, the impulse response decays to zero.
3. If one or more non-repeated roots of characteristic equation are on jω axis impulse response is bounded but the system is unstable.

Assertion (A): FET has characteristics very similar to that of pentode.

Reason (R): Both FET and pentode are voltage controlled devices.
