AM and FM radio are analog
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.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
DAC - Digital to Analog ConverterADC - Analog to Digital Converter
The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
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.
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.
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
the digital signal is converted to analog signal after using by transmitted antenna
AC - DC ... analog - digital ... frequency - phase shift ... AM - FM
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.
1.analog link have low SNR ratio whereas digital have high; 2.multichannel capabilities require high linearity optics ,whereas digital have good; 3.environment factors : moderate for AM and excellent for FM ,digital link have excellent

Digital
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
Unlike TV, there was no analog turn-off when radio stations added HD service. In the vast majority, their original analog service continues to work just fine.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
