Why do you get a staircase output in the quantization process of Pulse Code Modulation?

quantisation is the assigning the signal amplitudes to some levels,if amplitude is 4.8 we treat it as 5 and when it is 3.1 the output value is 3 thus we are assigning the amplitude to some reference levels thus corresponds to different amplitudes we get different quantisation output hence we get staircase signal


What is the power output of a 40 kg boy runs up a staircase to a floor 5 m higher in 7 s?

Power is the rate at which work is done, given by the formula Power = Work / Time. To calculate the power output, we first need to calculate the work done by the boy, which is equal to the product of his weight, the height of the staircase, and the acceleration due to gravity. After calculating the work done, we can then divide it by the time taken to run up the stairs to find the power output.


How do you estimate what output gas heater you require for your house?

Manual J heat load calculation. This is usually done at no charge as part of a contractors estimate.


How do you estimate glass wall cleaning prices?

It depends on the output. If the output was good and totally cleaned, I will give good price with tip, but if it's not, I will give the regular price.


How the efficiency of machine be obtained?

Efficiency is output power divided by input power. You somehow have to measure, calculate, or estimate both; the details will vary depending on the type of energy input and energy output.

What does the US produce 20 percent of in the world?

One estimate was that the US has 20 percent of the world's economic output, but estimates vary.


A 40-kg boy runs up a staircase to a floor 5 m higher in 7 s His power output is?

To find the power output of the boy, we can use the formula: Power = Work / Time. The work done by the boy in raising his body weight to a height of 5m is 40 kg * 9.81 m/s^2 * 5 m. This equals 1962 Joules. Thus, the power output is 1962 Joules / 7 seconds, which is approximately 280 Watts.

How is CO2 output calculated from kWh?

To calculate CO2 output from kWh, you would need to know the carbon intensity of the electricity source. This is typically measured in pounds or kilograms of CO2 per kWh. You can multiply the carbon intensity by the number of kWh consumed to estimate the CO2 emissions produced.
