Disvantages:
1) It's very costly depending on the system used, the number of detectors purchased.
2) Time consuming
3) Lack of qualified professional

Analogue to digital is a conversion process not a transmission process.
Usually digital, it is definitely less expensive to get highly accuracy with digital then analog. Also analog haas drift, stability, etc. problems that digital does not have.
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
digital signal is less susceptible to signal degradation due to the nature of it's transmission signal which is either on or off and therefore less errors occur as analog is prone to signal degradation and loss that is why digital tv is crisp and clear and analog is somewhat blurry in comparison, also with higher bandwidth achievable by digital transmission more data is able to be transmitted.
