Digital phones are more reliable than analog phones. The digital signals are easier to produce and the technology is more reliable than that of analog signal.
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.
No a digital only phone will not work with analog service, but there are analog/digital phones, I don't know if these are still offered but they were very popular because during the transition from analog to digital, digital coverage was not as good as analog so when you had no digital service it would switch to analog. so the only way to have analog service is if the phone is dual analog/digital or if you have a old analog only phone. you can always look up your phone to see if analog is supported.
Digital home phones are newer technology than the traditional analog phones. Digital has clearer audio than analog does and can transfer more data. This allows for more features like call display.

Digital phones are more secure, can send both voice and data transmission, and has better sound quality. Analog phones are less expensive and only transmit voice.
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.
led gives accuracy results
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
Digital phone signifies the dialing method in a particular phone. The dialing method can be digital or analog. The house phone can be digital, where you press buttons to dial a number or in rare case analog type where in you turn a number on a dial. All cell phones are digital.
ANALOG:continuous,rate of transmission is slow,less reliable 2 transmit,more noise,interference is more DIGITAL:non continuous,rate of transmission is fast,more reliable 2 transmit,less noise,interference is less
