Match the following:

Assertion (A): Silicon is less sensitive to changes in temperature than germanium.

Reason (R): It is more difficult to produce minority carriers in silicon than in germanium.

Assertion (A): The output of an 8 bit ADC is 80 H if input is 2.5 V

Reason (R): ADC has an output range of 00 to FF H if input range is - 5 to + 5 V

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.
4. p type semiconductor behaves as an insulator at 0 K.

Assertion (A): RF tuner is called front end of TV receiver

Reason (R): RF tuner receives the TV signal and selects the required channel.

1. If ensemble and time averages of a random process are identical, the process is ergodic.
2. If ensemble and time average of a random process are not identical, the process is ergodic.
3. An ergodic process is stationary.
4. A stationary process is necessarily ergodic.

Assertion (A): A fixed bias BJT circuit exhibits better performance as compared to a self bias BJT circuit.

Reason (R): A fixed bias BJT circuit used less components as compared to a self bias BJT circuit.
