Why FSk is good choice for low speed modem?
FSK is not always used for high-speed data communications, since it is far less efficient in both power and bandwidth than most other modulation modes. In addition to its simplicity, however, FSK has the advantage that encoded signals will pass through AC-coupled links, including most equipment originally designed to carry music or speech.
What are the advantages and disadvantage of pulse position modulation?
advantage-its a base for all the digital modulation technique disadvantage- 1.since amplitude keeps varying so there is noise associated with it. 2.due to nyquist criteria its require high bandwidth. 3.due to amplitude variation peek power of receiver also varies with it nitesh
Why angle modulation is called exponential modulation?
The reason it is called exponential (non-linear) modulation is that the information is encoded within the phase of carrier.
What is the number 475 on a ceramic capacitor?
encoded capacitor value in picofarads:47, digits5, zeros following digits4700000 pF or 4.7 µF
What is the advantage of ppm over pwm and Pam?
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
What is the relation between the bandwidth of a signal and after it has been encoded using spread spectrum?
there is no basic difference btw the BW. it is the same before & after the SS encoding

What is WML encoded in binary encoded to reduce bandwidth in wireless domain?
WAP Binary XML (http://www.w3.org/TR/wbxml/). Using WBXML with shared tables can cut size by upto 70%. Without shared tables, the size reduction is in the range of 50%. Note that the longer your tag names, the more savings WBXML will provide.
What is the suffix of encoded?
The suffix in the word encoded is -ed.
What is the suffix for encoded?
The suffix for encoded is "-ed".
Why is the colour sub carrier located at the higher end of the video bandwidth?
The original NTSC enhancement to support color mandated that black and white television sets be able to receive a color signal and display it as a black and white signal. Thus, all of the color information was placed at the top end of the video spectrum, and it was encoded in such a way that a non color sensitive Y decoder could still see the black and white portion of the signal without any problem.
What is a past tense of encode?
The past tense of "encode" is "encoded."
What is lacking in the sentence He was encoded the answer to the email message?
Encoded and it means "typed a message".
How many streams of audio can an encoded DVD contain?
8 Streams of audio can be encoded to a DVD.
What is the relationship between the bit rate of a signal before and after it has been encoded using DSSS?
In Direct Sequence Spread Spectrum (DSSS), the bit rate of the original signal is spread over a wider bandwidth by multiplying it with a pseudo-random noise (PN) sequence, known as the spreading code. This results in a higher chip rate, which is the rate at which the individual bits of the original signal are processed. Consequently, while the bit rate of the original signal remains unchanged, the effective transmission rate is increased due to the spreading, allowing for improved resistance to interference and better security. Therefore, the relationship is that the bit rate of the original signal is maintained, but the spread signal operates at a higher chip rate.
What is pre-encoded checks?
