1. Acceptor level lies close the valence band.
2. Donor level lies close to the valence band.
3. n type semiconductor behaves as an insulator at 0 K.

Assertion (A): When performance specifications are given in term of transient response characteristics, root locus method is a suitable method.

Reason (R): When performance specifications in terms of state variables are given, modern control methods can be used.

Assertion (A): For a dielectric, P = ∈₀(∈_r - 1) E.

Reason (R): Dipole moment per unit volume is called polarization of dielectric.

1. The modulator section and visual exciter can be solid state devices
2. VSB filter can be introduced at low power level
3. The subsequent stages following VSB filter can be tuned permanently for wideband linear operation
4. It is economical

1. Transit period is the time between two steady state
2. Transient Response is the response due to internal energy stored in circuit
3. Transit response is also called natural response
4. Transit response arises due to presence of C and L in the circuit
5. Transit is due to R, L, C in the circuit
