Assertion (A): In hybrid digital circuits the problem of logic race can occur.

Reason (R): In two level logic there is no problem of logic race.

Assertion (A): Schottky transistors are preferred over normal transistors in digital circuits

Reason (R): A Schottky transistor when used as a switch, between cutoff and active region.

Assertion (A): In computers the data is stored in hexadecimal form

Reason (R): Hexadecimal representation is short as compared to binary representation.

1. The intersection of root locus branches with the imaginary axis can be determined by the use of Routh criterion
2. Segments of real axis having an odd number of real axis open loop poles plus zeros to their right are not parts of root locus
3. The number of root locus branches terminating on infinity is always zero

1. Fewer tuned circuits
2. Greater limiting
3. Better linearity
4. Easy alignment
