Assertion (A): In an RC coupled amplifier the junction capacitances can be neglected at low frequencies but not at high frequencies

Reason (R): Capacitive reactance is inversely proportional to frequency.

Match the following:

Match the following:

1. Number of lines per picture 625
2. Interlace ratio 2 : 1
3. Aspect ratio 4 : 3
4. Channel bandwidth 8 MHz

Assertion (A): A good algorithm should be fast, require minimal computer memory and time.

Reason (R): Many times an algorithm is prepared in the form of a flow chart.

Assertion (A): The conductivity of an n type semiconductor increases with increase in temperature and increase in density of donor atoms.

Reason (R): Diffusion of carriers occurs in semiconductors.

Assertion (A): Microprocessors 8086 and 8088 are very similar in organisation and have identical instruction sets.

Reason (R): If clock speed is same the execution time of 8088 and 8086 are exactly equal.
