1. Thermistor is more sensitive than platinum resistance thermometer
2. The resistance of thermistor is solely a function of its absolute temperature whether the source of heat is external or internal
3. Thermistor has linear temperature-resistance relationship
4. Thermistor has linear negative temperature coefficient

1. Ports 1 and 2 are decoupled.
2. Port 3 and 4 are coupled.
3. A signal entering either port 1 or 2 splits equally between ports 3 and 4.
4. A signal entering either port 3 or 4 splits equally between ports 1 and 2.

Assertion (A): In a parallel in-serial out shift register data is loaded one bit-at a time

Reason (R): A serial in-serial out shift register can be used to introduce a time delay.
