Assertion (A): The Laplace transform of a ramp is 1/s².

Reason (R): The integral of a unit step function gives an impulse function.

1. The centre frequency is determined by the pitch of IDT comb shaped electrodes
2. The response can be modified shaping the overlap of comb electrodes
3. The response is maximum when acoustic wave has its wavelength equal to pitch
4. When a number of identical electrodes are arranged at the same pitch, the frequency characteristics of the filter is expressed by (sin x)/x

1. Registers are made of edge-triggered FFs, whereas latches are made from level-triggered FFs.
2. Registers are temporary storage devices whereas latches are not.
3. A latch employs cross-coupled feedback connections.
4. A register stores a binary word whereas a latch does not.

Assertion (A): In C it is possible for functions to call themselves.

Reason (R): C makes use of 'Pointers'.

Assertion (A): 2's complement arithmetic is preferred in digital computers

Reason (R): The hardware required to obtain 2's complement is simple.
