Path of the signal of television

Computers and Technology
1 answer:
AveGali [126]3 years ago

Answer:

⇓This is what I think personally⇓

Explanation:

The television signal wave form is actually a composite made up of three individual signals, as is shown in the figure. The first is a continuous sequence of electrical values corresponding to the brightnesses along each line. This signal contains what is known as the luminance information. The luminance signal is interspersed with blanking pulses, which correspond to the times during which the scanning spot is inactivated and retraced from the end of one line to the beginning of the next, as described above. Superimposed on the blanking pulses are additional short pulses corresponding to the synchronization signals (also described above), whose purpose is to cause the scanning spots at the transmitter and receiver to retrace to the next line at precisely the same instant. These three individual signals—luminance, blanking, and synchronization—are added together to produce the composite video signal.

early photographers who were first painters

Explanation:

The Rule of Thirds is a compositional technique which states that image painting, photograph, graphic design should be divided into nine equally proportioned boxes by creating a grid with two vertical and two horizontal lines. The rule of third helps in making the picture more attractive and balanced

The rule of thirds was first used in landscape paintings by painters as early as 1797.

In your opinion, what is an example of an innovative solution to an engineering problem? Explain briefly why you chose this answ
Mumz [18]

Explanation:

One of the things I’ve been writing and talking about a lot lately is the fact that solving problems collaboratively is an incremental process. In fact, in my book, Lost at School, I made mention of the fact that the model could just as easily have been called Incremental Problem Solving or Progressive Problem Solving. I thought the collaborative aspect of the model was the most important to emphasize, but that doesn’t mean that the incremental component isn’t almost as crucial. Often people who are new to the model enter the process of resolving a problem as if it’s a one-shot deal. If you have experience in using Plan B, you already know that most problems require more than one visit to Plan B to resolve. In other words, longstanding, complicated problems aren’t likely to be resolved the first time you try to discuss them. There’s a lot of information to be processed before a given problem can be solved. You need to gather information so as to achieve the clearest possible understanding of the kid’s concern or perspective on the problem (for the unfamiliar, that’s called the Empathy step). Then, you need to be clear about and articulate your own concern (that’s the Define the Problem step). Then, you’ll want to brainstorm with the kid so as to consider the array of potential solutions that could be applied to the problem and consider whether each solution truly addresses the concerns of both parties (that’s the Invitation). There’s a good chance you won’t even make it through all three steps of Plan B in the first attempt on a given unsolved problem (nor should you necessarily even try). If Plan B were a “technique,” then disappointment over not making it through all three steps in one conversation would be understandable. But Plan B is not a technique, it’s a process. As I’ve often emphasized, if you only make it through the Empathy step in the first attempt at Plan B on a given problem but you emerge with a clear sense of a kid’s concern or perspective on a problem that’s been causing significant angst or conflict, that’s quite an accomplishment. You’ll get back to the remaining steps at your earliest opportunity. There’s also an excellent chance the first solution you and the kid agree on won’t solve the problem durably. As you may know, this is usually because the original solution wasn’t as realistic and mutually satisfactory as the two parties first thought. But it could also be because the concerns weren’t as clear or simple as it first seemed. If a solution doesn’t stand the test of time, your goal is to figure out why, which means gathering additional information about the concerns of the two parties and why the solution may not be working so well. Plan B should always conclude with both parties agreeing to return to the problem if the solution being agreed upon doesn’t solve the problem durably. So if your enthusiasm for Plan B waned because your first solution didn’t stand the test of time, take heart: that’s not unusual. Many people enter Plan B with great hope, eager to see their new approach to helping a challenging kid pay quick dividends. In fact, Plan B may well pay quick dividends…not necessarily because the problem is yet durably solved, but because of the relationship- and communication-enhancing that occurs. And while the occasional problem – often simple ones – can be resolved with one visit to Plan B, now you know that several repetitions of Plan B may be necessary on each unsolved problem. Thanks for reading.

Vaselesa [24]

Answer:

Because it takes precision to a lot of things in tech and Eng. We need to measure all kinds of things, like wood, metal/etc. for computers and things that we use everyday, Because our world goes around being precise about things that we need everyday, like tables and things.
