Why A tradition phone line has a sampling rate of 2400 baud but a baud is not a bit while the data transfer rate of telephone line is greater then 2400 signal per second?
Baud rate is the number of samples per second. Data transfer rate is the number of bits per second. Since the analog phone line can have more than two values at any one sample, this translates to more bits per second than baud.
There is a tendency to confuse baud rate with data rate. The two terms are not always the same.

State sampling theorem?
sampling theorem is defined as , the sampling frequency should be greater than or equal to 2*maximum frequency, and the frequency should be bounded.. i,e fs=2*fmax where fs= sampling frequency
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 the Clipping circuit transfer function?
Transfer function is the relationship between output and input of a circuit. In the clipping circuit, the general transfer function is such that the transfer curve Av is less than 1 for passive limiter and greater than 0 to limit the maximum and minimum voltage value.
Explain quantitatively why the maximum power transfer curve is not symmetrical about the point where the source resistance equals load resistance?
when we look at the curve ,, we can see that before the peak point curve has greater slope as compared to the slope after the peak point .. the reason is PL is given as I^2RL ,,, current is a squared term here . before peak point current is greater so overall change in power is much greater but after peak point RL is greater and current is less now the load resistance is not a squared term... so slope will be less. therefore the curve is not symetrical
While discharging which is greater TPD or EMF?
EMF is greater
How does a sampling error affect the interpretation of your data?
The greater the sampling error the greater the uncertainty about the results and therefore the more careful you need to be in the interpretation.
State sampling theorem?

What are the merits and demerits of sampling methods?
Advantages and Limitation of Sampling: 1. Sampling saves time and labour. 2. It results in reduction of cost in terms of money and manhour. 3. Sampling ends up with greater accuracy of results. 4. It has greater scope. 5. It has greater adaptability. 6. If the population is too large, or hypothetical or destroyable sampling is the only method to be used. The limitations of sampling are given below: 1. Sampling is to be done by qualified and experienced persons. Otherwise, the information will be unbelievable. 2. Sample method may give the extreme values sometimes instead of the mixed values. 3. There is the possibility of sampling errors.
What is the advantage of sampling analog signal?
1-What are the advantages of sampling analog signals?2-what are the following terms mean : instantaneous Sampling , Natural Sampling , and Flat-top Sampling ?3- what are the advantages of digital communication over analog communication ?4-Explain the reason for making the sampling frequency greater than or equal to (2B)Hz , where B is the bandwidth of the analog signal
How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
What are the advantage of sampling over complete enumeration?
more expensive , less expensive ,less time consuming and greater accuracy
Is the best description of a stratified random sample?
Stratified random sampling is a form of probability sampling that provides a methodology for dividing a population into smaller subgroups as a means of ensuring greater accuracy of your high-level survey results. The smaller subgroups are called strata. Stratified random sampling is also called proportional or quota random sampling.
If fewer of individual from a population are chosen at random for an experiment group?
A it is lees likely that differences among them will destroy the test results B the chance of sampling error is unpredictable C the it is almost impossible that differences among them will destroy the test results D the chance OS sampling error is greater E the chance of sampling error is smaller
A monopoly permitted by and regulated by the government for its greater social good such as a telephone company?
natural monopoly
We have a population with mean of 100 and standard deviation of 28 take repeated samples of size 49 and calculate the mean of each sample to form a sampling distribution Is it a Normal Distribution?
a) T or F The sampling distribution will be normal. Explain your answer. b) Find the mean and standard deviation of the sampling distribution. c) We pick one of our samples from the sampling distribution what is the probability that this sample has a mean that is greater than 109 ? Is this a usual or unusual event? these are the rest of the question.
How does vasodiliation increase heat transfer to environment?
It increases the surface area of blood that is exposed to the environment, which means there is a greater heat transfer capacity - meaning heat transfer is increased.
What is a requirement for use of the hypergeometric distribution Only 2 possible outcomes Trials are independent Probability of a success is greater than 1.0 Sampling with replacemen?
FALSE. The probability of success (or anything else) cannot be greater than 1.0
