What are the ways to implement DAC and ADC?

ADCs are used to capture a large number of unknown signals and convert them into known descriptions. Instead, DAC takes a fully known, deeply understood description and then "simply" produces an equivalent analog value.

In short, DAC works in the domain of determinism, while ADC works in the domain of random input signals and unknowns, as long as the input is within the specified range.

In traditional signal processing theories, such as those described in Harry Trees' classic book Detection, Estimation, and Modulation Theory, signal processing faces varying degrees of challenge.

No, it's not a "fool" question or a brain teaser, and I think our readers are all very aware of the basic functions of analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

But there are also philosophical differences in how these converters are used and how people perceive them. In the simplest terms, an ADC is used to capture a large number of unknown signals and convert them into known descriptions. Instead, DAC takes a fully known, deeply understood description and then "simply" produces an equivalent analog value.

As described in Theory, signal processing faces varying degrees of challenge. For example, a signal whose characteristic parameters are already fairly clear (e.g., an analog signal modulated by AM) is much easier to evaluate than a signal that is filled with many unknown parameters (e.g., radar reflections that are disturbed by noise). So the ADC is indeed much more challenging than the DAC.

In order to get the most out of an ADC, especially for higher performance (speed or accuracy), a well-designed analog signal conditioning input channel is required, often with an ADC driver that is precisely matched to the ADC itself. The design of the DAC is much simpler. However, this relative simplicity should not make designers lax about DAC design.

In practice, it is easy for designers to pay insufficient attention to the analog output circuitry of DACs, such as slew rate, output drive (voltage, current, range), and load fault protection, which can easily lead to circuit and system-level headaches during prototype evaluation and product field application.

ADC was invented in 1913 when Nobel laureate Paul Ehrlich proposed the idea of the "magic bullet" in 1913. The DAC circuit was invented in 1920 by Sir Kelvin, and the ADC circuit refers to the analog-to-digital grade conversion circuit. That is, to change the analog signal into a digital signal.

It is generally used in data collection. An analog converter, also known as a DA converter, or DAC for short, is a device that converts digital quantities into analog. The da converter basically consists of four parts, namely the weighted resistor network, the operational amplifier, the reference power supply, and the cluster analog switch.

Analog-to-digital converters are generally used in digital-to-analog converters, and analog-to-digital converters are ADC converters, which are devices that convert continuous analog signals into discrete digital signals.
