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.
With analog and digital signals.
Electronics divides in analogue and digital one. Electronics is a physical branch of electron emission and behavior. Analog and digital are not two kind of electronics.
Power electronics is study about controlling the power using electronics devices, Electronics is study about controlling the electrons flow&make amplification of electrons for required areas
analogue, since it doesn't use electronics
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
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.
The difference between computer engineering and digital electronics is that digital electronics represents signals. Computer engineering integrates several fields of computer science and electrical engineering to make computer systems. Digital electronics is the field of computers and computer controlled devices including the ones with analog inputs and outputs.

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.
