A: square wave can be positive and or negative. A digital signal is a square wave but it can be of invariable duty cycles
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
The answer to the questions depends on where you are. In the recent change to digital in the UK, many existing analog aerials work perfectly with the new service although others have had to be changed. Generally, in areas where the digital terrestrial service is using similar frequencies to the analog service and where there is good signal strength, the old aerial is likely to work. The results will vary between countries and even between areas. Try it and see if your aerial still does the job.

It depends. A depletion MOSFET can be used as an ehancemnet MOSFET when it is operated as an analog amplifier. However, a depletion MOSFET can't replace an enhancement MOSFET when it is operated as a digital switch. When a depletion MOSFET is used as a digital switch, since the junction between source terminal and substrate must be reverse biased, the voltage of the source terminal of an N typde transistor must be tied to Vdd, and it is completely opposite to an enhancement MOSFET. When a depletion MOSFET is used as an analog amplifer, the source terminal and the substrate are both at the same potential, just like an enhancement MOSFET.

The digital divide refers to the gap between those who have access to technology and those who do not. The knowledge-gap hypothesis suggests that disparities in information flow through media contribute to existing social inequalities. In the context of digital technology, the digital divide can exacerbate knowledge gaps by limiting access to information and resources for marginalized populations.
In general, the more you compress the less you enhance.
The difference between digital boxes and digital adapters is that digital boxes can offer extra services such as Pay Per View, On Demand and Premium Channels such as HBO.

The difference between legal translation and business translation: legal translation is difficult and requires professional knowledge such as economic law, while business translation is relatively simple and has a lot of room for development.

The capacity is the difference between a laptop and a personal digital assistant. Personal digital assistance can't carry out all the functions that a laptop can do.
