Answer:

The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops

Explanation:

An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'

A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.

D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.

The following program segment is designed to compute the product of two nonnegative integers X and Y by accumulating the sum of

mote1985 [20]

The program is correct: at the beginning, product = 0. Then, we start summing Y to that variable, and we sum Y exactly X times, because with each iteration we increase Count by 1, and check if Count=X so that we can exit the loop.

The light you shoot in will dictate what shutter speeds to use.

Nesterboy [21]

Answer:

The three things that will determine your exposure are film speed, aperture and shutter speed. The speed of the film dictates how much light the film needs. The aperture controls how much light comes through the lens. And the shutter speed then controls how much of that light hits the film. These three things always work together to produce your image.

The shutter speed, sometimes known as exposure time, determines the amount of time your film is exposed to light when taking a photograph. So, you always need to balance your aperture and shutter speed to get a correct exposure.

The general rule is you need to shoot with at least 1/60 to get sharp images when shooting handheld. It is best to use a tripod if you want to shoot with a slower exposure time as this will help reduce any camera shake.

Fast Shutter

Fast speeds are really good for freezing fast-moving subjects. You need to make sure you are using a fast exposure time if you are trying to take a sharp image of a fast subject. Different cameras have different options but commonly you can choose something like 1/500.

Higher ISO film will also allow you to utilise the faster shutter speeds as they are more sensitive to light.

Slow Shutter

Slow shutter speeds will visibly record motion. They are often used to create the effect of motion in an image. A moving subject captured with a slow exposure time will be captured as a blur across the image. Slow exposure times are also necessary when taking photos at night. They allow you to get enough light to expose your image correctly.

Be careful when using slow exposures without a tripod. The slower the shutter the more likely that you will have visible camera shake in the image.

Reading Shutter Speeds

Shutter speed is measured in fractions of a second. So, for example, 1/60 is read as one-sixtieth of a second. The bigger the second number in the faster the speed.

Typical shutter speeds you will see are; 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250 and 1/500.
