Benefits digital antennas have over analog antennas include an increase picture quality, increase audio quality, higher number of channels from broadcasters, and automatic tuning.
The digital TV antennas were made when the analog satellites for TVs went to a Digital satellite. With a converter box and the digital antennas it still makes it possible to use TV that still use the old rabbit ears.
You can't tell just by looking at the antennas.
In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.
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.

Digital antennas usually cost around $40. However you can find cheaper digital antennas that are used.
