Assertion (A): An instruction cycle consists of fetch and execute cycles.

Reason (R): Fetch cycle has one machine cycle but execute cycle may have one or more machine cycles depending on length of instruction.

Assertion (A): In totem pole output the output impedance is low.

Reason (R): TTL gate with active pull up should not be used in wired AND connection.

Match the following:

Assertion (A): A non-sinusoidal wave can be expressed in terms of sine waves of different frequencies which are multiples of the frequency of fundamental.

Reason (R): If negative half of a complex wave is a reproduction of the positive half, the even harmonics are absent.

Assertion (A): In the circuit shown figure the diode is used to protect the active devices. Transistor T goes into saturation when a positive pulse is applied at base and non conducting

Assertion (A): Interfacing means synchronisation of digital information transmission between input output devices and computer.

Reason (R): A computer with higher bit word size executes programs at a faster rate.
