Why low frequencies are not used for data transmission in computer networks?
Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
Difference between drainage channel and irrigation channel?
A drainage channel is designed to remove excess water from an area, such as rainwater or wastewater. It is typically sloped to allow water to flow away from the area and may have a grate or cover to prevent debris from entering. An irrigation channel, on the other hand, is designed to bring water to an area for the purpose of watering plants or crops. It may be lined with concrete or other materials to prevent erosion and may have gates or valves to control the flow of water.
What is a cavity combiner in a communication system?
A Cavity Combiner is a device which allows the outputs of two or more transmitters on different frequencies to be combined. It uses bandpass filters on each input to prevent the signals from the other transmitters from entering the output of a transmitter.
How do you code for a purse string closure?
To code for a purse string closure, start by creating a channel along the top edge of your fabric piece where the string will run. This can be done by folding over a portion of the fabric and stitching it down, leaving an opening at one end for the string to be fed through. Once the channel is prepared, use a safety pin or a bodkin to thread a strong cord or string through the channel. Finally, secure the ends of the string to prevent it from slipping out, and gather the fabric by pulling the string to create the closure.
How do you make a canal?
To make a canal, first, survey the land to determine the best route, considering factors like elevation and water source. Next, dig the channel, which may involve excavation and earthmoving equipment, while ensuring proper width and depth for water flow. After the channel is formed, reinforce the banks to prevent erosion and allow for drainage. Finally, connect the canal to a water source and manage the flow with gates or locks as needed.
What is purpose of guard band?
Also called a frequency guard band, a narrow frequency band between adjacent channels in multiplexing that is kept unused to prevent the channels from overlapping and causing crosstalk among modulated signals. Guard bands are commonly used in FDM but are also used in any data transmission method that relies on frequencies.
How much minimum bandwidth is required for multiplexed channel?
The minimum bandwidth required for a multiplexed channel depends on the number of channels being multiplexed and the bandwidth of each individual channel. In general, the total minimum bandwidth needed is the sum of the bandwidths of all the channels being combined. For example, if you are multiplexing four channels, each requiring 1 MHz, a minimum bandwidth of 4 MHz would be necessary. Additionally, some multiplexing techniques may require guard bands to prevent interference, which would increase the total bandwidth requirement.
Do Stable allele frequencies prevent microevolution?
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.
Why low frequencies are not used for data transmission in computer networks?
Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
Does GPS satellite have the same frequency with AIS?
No, GPS satellites use L-band frequencies around 1.5 GHz while AIS uses VHF frequencies around 162 MHz. Both systems operate in different frequency bands to prevent interference.
Who can we prevent roofs from water?
The sloping roof of a house is covered in an overlapping covering of slates or tiles, forming a waterproof weather protection.
How do insert a transition without it overlapping the next 'slide' in Microsoft Movie Maker?
You can't do that in any video editing software that I know of. The whole concept of a 'transition' is 'movement from one frame to another'. Therefore, you can't prevent a transition from overlapping the next frame.
What are the effects on the human ear when exposed to hearing different frequencies?
Exposure to different frequencies can affect the human ear in various ways. High frequencies can cause hearing loss and damage to the delicate structures in the inner ear, while low frequencies can cause discomfort and distortion in hearing. It is important to protect your ears from prolonged exposure to loud sounds at any frequency to prevent long-term damage.
How should one properly tape their feet to prevent blisters?
To prevent blisters, properly tape your feet by using adhesive tape or moleskin to cover areas prone to friction. Make sure the tape is smooth and snug, but not too tight. Avoid overlapping tape to prevent rubbing.
Do parental controls keep you from seeing your channel stats on socialbladecom?
The parental controls goes not in any way prevent you from seeing the channel stats on socialbladecom. The parental controls only help the parents prevent their children from watching certain channels.
Where do venous valves channel blood?
They prevent back flow and help to return blood to the heart.
Does taking a calcium channel blocker prevent the extra calcium taken for bone loss going to the bones?
No, calcium channel blockers work at the level of muscle cells.
