Both, Like any other form of communication. However, all analog forms of communication/transmission will end in February of 2009. All manufactures have already changed to the digital format, therefore in a couple of months any older system will be obsolete.
It isn't always. Baseband analog signals have no carrier.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.

Analog and digital signals can both be transmitted wirelessly. Wireless internet (Wi-Fi), for instance, uses digital. AM and FM Radio uses analog. Cell phones are digital. Cordless phones can be digital or analog.
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
It isn't always. Baseband analog signals have no carrier.
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.

Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.

The difference between baseband coaxial and broadband coaxial cable is baseband coaxial technology uses digital signaling in which the cable carries only one type of digital signal. Where as the broadband coaxial technology typically transmits analog signals and is capable of transmitting multiple frequencies of data simultaneously.
