Why we need to convert analog to analog conversion?
Analog-to-analog conversion, or analog modulation, is the representation of analog information by an analog signal. Modulation is needed if the medium is bandpass in nature or if only a bandpass channel is available to us. The analog signal produced by each station is a low-pass signal, all in the same range.
This modulation is generally needed when a bandpass channel is required.

Re: Answer the question and discuss
Analog-to-analog conversion, or modulation, is the representation of analog information by an analog signal. It is a process by virtue of which a characteristic of carrier wave is varied according to the instantaneous amplitude of the modulating signal. This modulation is generally needed when a bandpass channel is required. Bandpass is a range of frequencies which are transmitted through a bandpass filter which is a filter allowing specific frequencies to pass preventing signals at unwanted frequencies.
Any digital processor, like a computer, needs digital input for processing, transporting and storing data. ... The output is required in analog form and for that a DAC (digital analog converter). It converts digital output into analog output so that it is meaningful for the user.
