What Steps to take when selecting a suitable sampling frequency?
The Nyquist Theorem says that the sampling frequency should be twice the bandwidth to avoid aliasing. Thus if the bandwidth of the system is bw then the sampling frequency f=2*bw.
When analog voice signal converts into digital signal the bandwidth needs 64kbps. Why?
PCM technique is used to convert analog voice signals into digital. In PCM the analog frequency is first sampled and then converted into binary bits. Each samples are taken as 8bits long. Basic communication theory requires that a minimum sampling rate of twice the frequency of the signal to be sampled will result in an accurate representation of the original signal.Human voice can have max 4000hz frequency, therefore sampling rate should be 8000 samples/sec.Which implies required bit rate for transmitting voice is 8000*8 = 64000 bits/sec = 64kbps.
When paralleling two AC generators the frequency of the incoming machine immediately prior to closing its breaker should be?
The frequency must be the same and the phase must be the same as well. This can be indicated by having a lamp connected across the switch (for each phase if 3-phase).
Why does the existence of a cutoff frequency in the photoelectric effect favor a particle theory of light rather than a wave theory?
According to the wave theory, light of any frequency can cause electrons to be ejected as long as the light is intense enough. A higher intensity corresponds to a greater electric field magnitude and more energy. Therefore, there should be no frequency below which the photoelectric effect does not occur. According to the particle theory, however, each photon carries an amount of energy that depends upon its frequency. Increasing the intensity of the light increases the number of photons but does not increase the energy of the individual photons. The cutoff frequency is that frequency at which the energy of the photon equals the work function. If the frequency of the incoming light is below the cutoff, the electrons will not be ejected because no individual photon has enough energy to impart to an electron.
What is the 60 Hz on a welder with the listed input as 208 230 volt single phase 60Hz?
60 Hertz is the frequency that the welder should be connected to, to work as it is designed to.
Why is Radio Frequency used in mobile communication?
the frequency used in mobile communication should be greater then 30mhz so cannot be reflected by the ionosphere thats why we are using a frequency of range less ghz so called "radio waves"

What is Quo-band?
Perhaps, you misspelled it. It should be Ku band, a high frequency band used for beaming satellite signals, including Television channels.
What are ethics in oral communication?
Ethics" can be defined as the critical, structured examination of how we should behave --- in particular, how we should constrain the pursuit of self-interest when our actions affect others
5 W's in communication?
What / Why: What are you communicating and why are you communicating? This will be the content of your communication.Whom: Whom should your address the communication to? Should you communicate to specific individuals or groups or the whole company?Who: Who should communicate the message? Am I the right person to communicate the message?When: When is the right time to communicate? When also refers to the frequency of communication. Some messages may need multiple reminders.Where: Where do you communicate the message? Do you do it in a town-hall meetings or in person meeting or via email?

What is the uplink frequency of a satellite?
Uplinking refers to the transmission of a signal via a satellite from one terrestrial location to another location and then ultimately the signal can be distributed to the end users.What is the role of uplinking in the entertainment sector?In broadcasting, broadcasters use uplinking to beam their programmes to their viewers across countries. Typically, they hire the services of a transponder or a transponder itself that will be used to beam the broadcaster's programmes to the receiving country.What is the Indian policy on uplinking?Till some time ago, there were restrictions on uplinking from India. In July 2000, the government liberalised uplinking and allowed Indian companies to set up their own teleports to uplink directly from India. Television channels were also allowed uplinking facilities. The foreign equity holding of such companies should not exceed 49%.The frequency of uplinking varies from user to user according to band assigned. Many upling frequency is 4mhz in c band and 10 mhz in ku bandGenerally uplinking and downlinking frequencies are kept different in order to minimise interference and distortion.For details mail meSanidhyagenioushunk@gmail.com
Under what circumstances should you use a grouped frequency distribution instead of a regular frequency distibution?
You should use a grouped frequency when you have a wide range of scores.
Why should listening be taught?
Listening should be taught because it is a crucial communication skill that helps individuals understand others, build empathy, and develop stronger relationships. Teaching listening skills also improves comprehension, critical thinking, and problem-solving abilities. It is essential for effective communication in both personal and professional contexts.
What color should a space satellite be?
Spacey.
Should electronic communication in the classroom differ from electronic communication outside the room?
Yes. There should be no electronic communication in the classroom.
can i gt satellite tv in my area?
