What are the advantages of FSK?
-> frequency shift keying promotes long distance communication. ->it has high security. ->low noise ->efficiency is high. ->decoding of signal is easy.
Why a given generator frequency is dictated by the size of the magnetic flux?
A generator's frequency is dictated by the power system frequency, and the number of poles in the generator. For 60 Hz power and a generator designed with two poles, the generator must turn at 3600RMPs (60 Hz * 60 seconds / minute). The magnetic flux is what induces the current in on the output winding. Spinning a synchronous generator faster or slower is not done to control the magnetic flux. The field winding voltage is varied to control this, and in turn control the output of the generator.
When you rotate the handle of the electric generator faster does it deliver more less or the same voltage?
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
Why scope frequency is always greater then signal frequency in the oscilloscope?
In the course of sampling a signal to graph the parts of a repeating event on the display, the sampling must be done faster than the event you want to graph. If the sampling is done slower than the event then you will be displaying several parts of the event in a single dot on the display, highly inaccurate. The signal sampling must be done fast enough to display the event in enough detail. The higher you set the scope frequency, the wider the event appears on the display, possibly losing the sides of the event if you go too high.
What is difference between npn ans pnp transistor?
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.
Is wireless networking faster than traditional networking configuration?
Depends on your wireless protocol vs your physical port speed. But typically, a wired connection is best if connecting to the same router.
If you make a musical instrument shortter will it have a high or low frequency?
That would surely depend on the specific instrument, and the way it produces its sound. Two examples:A shorter string will vibrate faster, and therefore produce a higher frequency.Similarly, the air in a shorter tube will vibrate faster, and therefore produce a higher frequency.
Why very low frequency is having no use for data transfer in computer network?
Low frequency devices are losing popularity in computer networking because of their slow transfer rates. The higher the frequency of a device the faster it can transfer data.
What is faster LAN or Wireless?
LAN is a collection of computers with in certain distance say, a building or premises or within a city. A LAN can be a collection of wired computers or wireless computers or mixed. A wireless connection is a connection which uses radio frequencies to send and receive data, e.g. a mobile phone is an application based on wireless connection.
Which is more faster wired Internet or wireless Internet and why?
Wired internet is faster as it works in full duplex mode (can send and receive at a time). Wireless works using half duplex mode, requires a middle device (like access point) for transmission and various other factors like devices using the same radio signal frequency (2.4 GHz) affect its transmission
What are the factors governing frequency of updating?
The faster the thing changes the faster the frequency of updating
What increaases the frequency of a pendulum?
Length of the pendulum (distance of centroid to pivot) - shorter is faster. Gravitational or acceleration field strength - more is faster.Note: The mass of the pendulum is not a factor.
Do waves with a shorter wavelengths travel faster than waves with longer wavelengths?
The physical length, short wavelengths are shorter than long wavelengthsThe frequency, short wavelengths are higher frequency than long wavelengthsThe energy per photon, short wavelengths have more energy per photon than long wavelengths
Ethernet Cables: Reliable Home Networking?
There are several connection options for home networking. The first and traditional option is to use network cables, such as Ethernet types. The second option is to have a wireless network without the need for any cables. Either way, modern wireless routers support both types of networking methods. However, Ethernet cables offer several advantages over wireless networking. For example, Ethernet cables have much faster speeds of data transmission compared to routers. Additionally, there is always a reliable transmission of data through cables while wireless signals could be effected by physical barriers and interference from other radio waves. Also, Ethernet cables are available in a variety of lengths while wireless routers have a fixed range.
Whose faster between a taller person or a shorter person?
Shorter
Why does the pitch change when you press the strings on a bass?
Because when you press on a string it shortens the vibrating part of the string, producing a higher tone. Shorter strings produce a faster vibration or frequency.
Which is faster wifi or wireless n with card?
wireless n is a type of wireless internet ("wi-fi)
