What is narrow band modulation frequency?
When the frequency sensitivity of the modulating signal is small,the bandwidth of the FM is narrow. The narrowband FM has one carrier term two sideband terms.The modulation index is also small compared to one radian.
What are the advantages of digital data compared to analog data?
Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.
What is the simplest form of load balancing?
Outbound bandwidth aggregation - the WAN link controller should provide both inbound and outbound bandwidth load balancing and failover. The user defines weights (bandwidth capacity) based on the bandwidth of each WAN link. When a session is generated from the LAN, the device computes which link has the most available bandwidth and routes traffic from that session over that particular WAN link. The device typically allows the selection of two link load balancing algorithms: 1. Symmetrical round robin - routes sessions to all links in a round robin manner. 2. Intelligent (weighted) load balancing - computes a ratio between the weight (bandwidth capacity) of the different WAN links, and then routes sessions accordingly. That is, the faster the link, the more sessions that will be sent over that link, in order to make the most efficient use of all the bandwidth available. Additionally, an intelligent link load balancing solution like the Ecessa PowerLink load balancer will examine the amount of real-time traffic on each link, compared to the amount of available bandwidth resources left, and choose the best path for the next session's most optimal route for performance. Incoming bandwidth aggregation - is accomplished by the WAN link controller acting as the authoritative DNS server for the domain. The device advertises all available WAN links to the DNS cache servers which in turn resolve the domain names to queries in a round robin format. In this manner, all externally initiated sessions are load balanced over all available links. Since the device is resident at the domain site and is able to directly monitor the link status, failed links are removed from the DNS tables immediately upon failure. By setting the host name record Time-to-Live (TTL) to a short period, the DNS caching servers will flush their address tables and will update them from the device regularly, and thus be informed when a link fails.
What is the difference between yagi antenna and dipole antenna?
I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.
What is hybrid seed technology?
In hybrid seed production, the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis. To produce hybrid seed, elite inbredvarieties are crossed with well-documented and consistent phenotypes (such as yield) and the resulting hybrid seed is collected.
What is narrow band modulation frequency?
When the frequency sensitivity of the modulating signal is small,the bandwidth of the FM is narrow. The narrowband FM has one carrier term two sideband terms.The modulation index is also small compared to one radian.
What is a difference between broadband ISDN and narrowband ISDN?
Here are some differences between broadband ISDN and narrowband ISDN: 1) Narrowband ISDN uses 64 kb/s channel, while broadband ISDN uses 100 mb/s channels. 2) Broadband uses call relay, while narrowband uses frame relay. 3) In narrowband, ISDN information carries narrow frequency, while in broadband, ISDN uses a wide band of frequency.
Is low bandwidth signal has more power than high bandwidth signal?
no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.
What are the disadvantages of spread spectrum technique signal?
Some disadvantages of spread spectrum technique signals include increased complexity in design and implementation, higher power requirements, and potential interference with other systems using traditional narrowband techniques. Additionally, spread spectrum signals may have reduced data rates compared to narrowband signals.
What signal has wider bandwidth sine wave with frequency 100HZor 200HZ?
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
What are the benefits of using round bladed butter knives compared to traditional butter knives?
Round bladed butter knives are easier to spread butter evenly and smoothly on bread or toast. The rounded edge allows for a more controlled and precise spreading motion, resulting in a neater and more aesthetically pleasing presentation. Additionally, the rounded blade reduces the risk of tearing or ripping the bread while spreading, making it a more user-friendly option for spreading butter.
What is the advantage of qpsk over psk?
QPSK (Quadrature Phase Shift Keying) allows for double the data transmission rate compared to PSK (Phase Shift Keying) for the same bandwidth. Additionally, QPSK is more resilient to noise and interference compared to PSK, making it a preferred choice for communication systems in noisy environments.
Which type of wave spreading do you think causes faster energy loss-two dimensional?
In two-dimensional wave spreading, energy loss is typically faster with cylindrical spreading, where the wave energy spreads out in a circular pattern. This is because more energy is dispersed to the sides compared to spherical spreading, which is more evenly distributed in all directions.
What ridge has the slowest rate of seafloor spreading?
The Mid-Atlantic Ridge has one of the slowest rates of seafloor spreading, averaging about 2.5 cm per year. This ridge is located in the Atlantic Ocean and is less active compared to other spreading ridges like the East Pacific Rise.
What is the best type of medium for open-ended bandwidth needs?
Fiber optic cables are the best type of medium for open-ended bandwidth needs due to their ability to transmit data at high speeds over long distances without degradation. Fiber optics have a much higher bandwidth capacity compared to traditional copper cables and are highly reliable for transmitting large amounts of data.
Why is the bandwidth of DPCM is greater than PCM?
in pcm entie sample is sent.. where as in dpcm the difference between the predicted value and the original sample is sent which will be smaller when compared rto the original sample..
How did research from the Glomar Challenger help scientist support the theory of seafloor spreading?
Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.
