Assertion (A): The resistivity of intrinsic semiconductor decreases with increase in temperature.

Reason (R): The forbidden gap decreases with increase in temperature.

1. It is of non-minimum phase behaviour
2. It normally exists in thermal, hydraulic and pneumatic systems
3. It has an excessive phase lag with no attenuation at high frequency

Assertion (A): Magnetron is generally used in n mode.

Reason (R): Frequency for p mode can be easily separated from adjacent modes.

Match the following:

1. Arithmetic operations can be performed on ints.
2. Arithmetic operations can be performed on floats.
3. Arithmetic operation can be performed on chars

Assertion (A): Holes are majority carriers in p type semiconductor.

Reason (R): In p type semiconductor, the electrons produced by thermal agitation recombine with holes.

Assertion (A): In simplifying block diagram the product of transfer functions in feed forward direction must remain the same.

Reason (R): In simplifying block diagram the product of transfer functions around a closed loop must remain the same.
