Voltmeter Construction

With an amp clamp amps appear on the vertical axis. The scope obtains this type of reading from the magnitude of AC and additionally the phase and waveform can also be

Introduction: In this assignment, I will explain the role of hardware and software components within a computer system. Furthermore, I will explain how they relate to digital graphics.I will also recommend suitable components for Cambridge Industrial Design. (P1)

A Delta Sigma modulator converts an analog input signal to a Delta Sigma modulated digital bit-stream. A first-order Delta Sigma modulator consists of an analog integrator, a one-bit ADC, and a one-bit digital to analog converter (DAC), as shown in Fig. 2. In the Delta Sigma modulator circuit, the analog input port and the digital output port can use either dual power supplies or a single power supply. To avoid confusion, we use P and N to represent the polarity of the output digital signals. P means a digital positive value “true", while N means a digital negative value “false". We use numbers to represent digital or analog levels. For example, −1 and +1 represent the dual power supply level VSS and VDD, respectively. 0 means analog ground, which is 0 volts in a dual power system.

Next, a linear graph of voltage vs. current was collected by turning the voltage between 0.25 V and 0.50 V, then increasing it to slowly approach the maximum voltage value. By doing this, current values were collected for several voltage intervals. All values for this procedure were recorded in a table and plot and are shown in the data section. A linear regression of the voltage vs. current data was then taken to find the experimental resistance value.

A scientist would need a glass tube with positive and negative electrodes. The tubes were called cathode tubes, and they were common in the late 1890s. The air leaves the glass tube, and a florescent glow is produced when a high voltage runs through the tube. The scientist needs to cover the glowing tube with a heavy, black paper or cardboard. Then the scientist will see the green colored fluorescent light illuminating from the box. This is known as the X-Rays which energizes the phosphorescent materials in the room. The newly discovered ray would pass through objects, and it can cast a shadow of most solid objects. The ray consists of electron passing through the matter underneath the cathode tube. It can pass through human tissues, but it cannot pass through bones and metal

The type of measurement that I was able to record with the most number of significant figures was the mass. To measure this, I used an electric scale which showed up the the 0.001 place, and when objects were placed on it, it showed at least 4 significant figures. The exactness of these measurements mean that they were precise.

The X-Ray was invented in 1895 by Wilhelm Conrad Roentgen. It all started with a vacuum tube called a Crookes tube, with this Roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the photograph of his wife’s hand with a ring

After the x-ray has been taken, the image receptor can then be removed from the table and placed into the Fujifilm capsula CR reader. This will scan the receptor and display the image on the computer monitor.

X-ray strike on intensifying screen; light is then emitted and the film will exposed to light

He observed that when he switched the high voltage supply on, the screen started to emit a faint green glow. He repeated the experiment several times to be sure that it was the “invisible” light from the Crookes tube that was responsible for the green glow on the screen. Consequently, he started setting-up obstacles between the Crookes tube and the screen to study which materials blocked these new rays. One day he accidentally stuck his hand between the tube and the screen and saw an eerie outline of his bones: the first radiograph as recorded in history. Astonished by his own findings, he spent the next 6 weeks studying the properties of the now-called X-Rays. He analyzed his results and published his paper “On A New Kind Of Rays” in December 1895, which marked the beginning of a scientific revolution. After the discovery of the electrons in 1897, scientists finally developed a theory about the production of X-Rays. When high voltage was applied across the anode and cathode of the Crookes tube, electrons from cathode got attracted by the anode. While travelling through the vacuum these

it is comprised of a non-magnetic, thin metal rod or needle freely pivoting on an insulated post. The needle is a conductor which means it's free-electrons will respond to the presence of any charged objects. To begin we touch the Versorium with our hands to discharge it. We have 2 insulating rods, one made out of PVC and the other one made out of Clear Plastic, which we will charged by rubbing materials like Rabbit Fur, Cotton, and Silk. You want to grab the PVC rod and rub it with the Rabbit Fur and the put it near the Versorium and see how it reacts. Touch the Versorium to discharge it and try a different material and the different rod. Repeat the last step until you have tried every combination. Record what you see with different combinations or rod and

intervals to 125 ms. The in-plane spatial resolution of the MSCCT scanner is nine line

The CBCT is somewhat recent imaging modality, as the first commercial scanner being in use in 1998 for dental imaging aims (87). This is a subtype of computed tomography which utilizes an x-ray beam in the form of cone instead of the conventional fan one (88). For standard full field of view for CBCT, polychromatic X-rays are generated from a source tube generated by 100-120 kV tube potential using 1.5-10 mA current (89). The generated X-ray photon energy is absorbed by different materials found be¬tween the X-ray source and detector. The remaining energy after materials absorption is recorded on a film detector as expressed by intensity (I) that means energy per area and time. For example, the flat-panel detector consists of a pixel array

These are called flat panel as well, When comparing monitors designed using liquid crystal display with monitors designed using cathode ray tube the following characteristics can be noticed in LCD’s

(AI) channels, two analog output (AO) channels, 12 DIO channels with a full-speed USB interface. Here, it has two parts, one comprises analog input pins (1 to 16) and alternate side has the digital input pins (17 to 32). AIx pins are the input channels where input analog quantities are to be given whereas AO pins are the output channels where the output is to be obtained.
