75uS is the time constant used for a high-pass filter to enhance the high frequency audio before transmission to help reduce noise upon reception. The PLL is the portion of the IC which locks your chosen transmission frequency to the crystal reference X1. The PLL portion also contains an oscillator circuit which works in conjunction with the external parts of D5 and the STUB (that weird trace on the back of the board). D5 is called a varactor diode, and is a special variety of diode that is connected backwards. As a reverse DC voltage is applied across the diode, its capacitance varies.
4. Light can be refracted Light rays do not just change direction when they strike a reflective surface. They also change direction when they pass from one medium to another. 5. Light is absorbed 6.
7. You want to build a circuit which causes a ligh tbulb to turn on when you throw a switch. So, you build the circuit if Figure 5. When the switch is connected to point A the capacitor charges, and when you connect the switch to point B the light goes on. Let the resistance of the light bulb be Rℓ = 1.50 ×103 Ω, the potential difference across the battery is VB = 10.0V , and the capacitor has a capacitance of C = 1.35 × 10−4 F
The traffic sent and received for the PK256_100Mbps are pretty much right on. I would believe them to be the same. 2 8. For the PK512_100Mbps run compare the total traffic sent to the total traffic received. Are they the same?
See signal-to-noise ratio. Fundamental physical limits such as the shot noise in components limits the resolution of analogue signals. In digital electronics additional precision is obtained by using additional digits to represent the signal; the practical limit in the number of digits is determined by the performance of the analogue-to-digital converter (ADC), since digital operations can usually be performed without loss of precision. The ADC takes an analogue signal and changes into a series of binary numbers. The ADC may be used in simple digital display devices e. g. thermometers, light meters but it may also be used in digital sound recording and in data acquisition.
| Medium | Light travels at different speeds in different mediums, as they can be more or less dense. This means that the refraction and wave speed will be altered when it hits the lens. | Colour of light | Different colours of light have different wavelengths and frequencies causing them to refract different amounts at different focal points. | Material | Depending on the material depends on how much the light will refract, as if you used ice it would refract less increasing the focal length compared to glass as ice is less dense.
Use the report pages below to record your data. Answer questions A-G found on pages 46 and 47. Name: _________________________ Lab 2 Report Data: Data Table 1: Length Measurements | Object | Length (cm) | Length (mm) | Length (m) | CD or DVD | 12.1 cm | 121 mm | .121 m | Key | 5.1 cm | 51 mm | .051 m | Spoon | 16.1 cm | 161 mm | .161 m | Fork | 18.5 cm | 185 mm | .185 m | NOTE: The instructions indicate to measure the objects to “one degree of uncertainty.” The degree of uncertainty is a property of the instrument used. All three recorded values will have the same precision. On page 29 is the explanation of uncertainty.
If there are higher levels of potassium, then the resting membrane potential will be less than normal and an action potential will be not likely with the same amount stimulation. More voltage is needed. • Explain how hypokalemia will initially affect the resting membrane potential and the generation of an action potential. The resting membrane potential is based on the polarization of the cell. If there are lower levels of potassium, then the resting membrane potential will be higher than normal and an action potential will be more likely with less stimulation.
The reaction center contains chlorophyll a. The role of pigments is to catch the wavelengths of light. In Exercise 4B, the function of DPIP will be reduced when light strikes the chloroplasts and the electrons will be boosted to higher energy. In this experiment NADPH is replaced by DPIP. The source of electrons that will reduce the DPIP is light.
C. 0.853 s D. 0.925 s Don't panic. Use the calculated settings for Relay A, and calculate the response time of relay A for a fault current of 8075A. i.e. PSM=8075/(ES A), then get t(TSM=1pu), then multiply this time by the set TMS A to get the required response time of relay
