(a) (i) followed by(ii)

(b) (ii) followed by (i)

(c) (iii)

(d) (iv)

Answer:

The correct options are:

(a) (i) followed by(ii)

(b) (ii) followed by (i)

(c) (iii)

Explanation:

The band pass filter removes the signal’s undesirable frequencies.
The frequency response of a circuit is the fluctuation in its behavior as the frequency of the input signal changes, indicating the frequency range across which the output (and gain) remains relatively constant.
As a result, the frequency response curve (figure) for the filter circuit used to generate AM waves should be fig (ii) followed by fig (i) with fig (iii) being proper as well.
