Answer:

EMI, and RFI

Explanation:

EMI stands for Electromagnetic Interference when in the radiofrequency spectrum can also be known as Radio-Frequency Interference (RMI).

An unshielded ethernet cable (which is made of copper) can act as an antenna, any noise that leaks to it will cause an interference with the signal, and thus causing data corruption and signal distortion.

A signal has a spectrum from 0 to 145 Hz, as shown below. It is sampled at a rate of 295 Hz. Find the region of the baseband spe
kirza4 [7]

Answer:  None; all will be recoverable

Explanation:

If a signal (band-limited) is sampled at regular intervals, it could be recoverable or not, based on the number of samples taken.

Let's assume that we want to take samples of a simple sinusoid; If we take more than two samples during a signal cycle, the original waveform will be able to be reconstructed, just passing the sampled waveform through a low-pass filter.

In the more general case in which the signal occupies a frequency spectrum, if the sample frequency is greater than the double of the highest frequency in the spectrum, the signal can be retrieved completely, according to the  Nyquist Theorem.

In this case , as the highest frequency is 145 Hz, it would be enough  to take samples at a rate greater than 290 Hz; As the sample rate is 295 Hz, all the signal can be recovered, at least, using an ideal "brickwall" low-pass filter.

Create a program that compares the unit prices for two sizes of laundry detergent sold at a grocery store.
astraxan [27]

Complete Question:

Create a program that compares the unit prices for two sizes of laundry detergent sold at a grocery store. Console Price Comparison Price of 64 oz size: 5.99 Price of 32 oz size: 3.50 Price per oz (64 oz): 0.09 Price per oz (32 oz): 0.11

Using Python

Answer:

<em>This program does not make use of comments (See explanation section)</em>

price64 = float(input("Price of 64 oz size: "))

price32 = float(input("Price of 32 oz size: "))

unit64 = price64/64

unit32 = price32/32

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

if unit64>unit32:

     print("Unit price of 64 oz is greater" )

else:

     print("Unit price of 32 oz is greater" )

Explanation:

This line prompts the user for the price of 64 oz size

price64 = float(input("Price of 64 oz size: "))

This line prompts the user for the price of 32 oz size

price32 = float(input("Price of 32 oz size: "))

This line calculates the unit price of 64 oz size

unit64 = price64/64

This line calculates the unit price of 32 oz size

unit32 = price32/32

This next two lines print the unit prices of both sizes

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

The next line compares the unit prices of both sizes

if unit64>unit32:

This line is executed if the unit price of 64 oz is greater than 32 oz

     print("Unit price of 64 oz is greater" )

else:

This line is executed, if otherwise

     print("Unit price of 32 oz is greater" )
