digital systems are nothing but may be based on microcontroller, or an electronics parts which are highly sensitive, fast response and light in weight. Where as analog instruments mainly consists of mechanical parts which indicates lower accuracy compared to digital.

You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.
Digital-to-Analog Converters (DAC) and Analog-to-Digital Converters (ADC) are essential for interfacing between the digital and analog worlds. DACs convert digital signals from computers or processors into analog signals, allowing us to drive speakers, displays, or other analog devices. Conversely, ADCs convert analog signals, such as sound or light, into digital signals for processing, storage, or analysis by digital systems. Together, they enable seamless communication and interaction between digital devices and the real-world analog signals they monitor or control.
Analog signals are continuous while digital signals are discrete

Analog signals are continuous while digital signals are discrete
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
Analog instrument are interface with digital instrument with the help of analog to digital converter(ADC).ADC converts analog signals to digital signals.
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.

The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.
It's usually analog, but digital signals can be converted, if needed.
Analog system simulation is more sensitive to the changes in the parameters compared to the digital system. This is because of the continuous nature of the analog signals, unlike the discreet nature of the digital signals. Digital systems have gates which can not be used in Analog system.
