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.
Answer:
Hot-add
Explanation:
The computer system is a electronic device that is used to perform computational task on input data for a pre-dertermined result. The components of the computer is divided into hardware and software components.
The hardware components are the physical parts of the computer system, while the software component are the instructions that runs the system.
The RAM is a physical component that provides memory for running current activities on the monitor screen. When it is removed or faulty, the screen goes blank. To add more RAM memory to the system while the system is on, activate the hot-add memory settings.
Answer:
def encrypt_digit(digit):
if type(digit) is int or float:
digit = str(digit)
hold = list()
for x in digit:
d = str((int(x) + 3)%10)
hold.append(d)
first = hold.pop(0)
second = hold.pop(0)
third = hold.pop(0)
fourth = hold.pop()
print(int("".join([third,fourth, first, second])))
encrypt_digit(7836)
Explanation:
The python function accepts a four-digit parameter which represents the data transmitted over the company's telephone network. The function encrypts the data by adding 3 to each digit and getting the modulus of division 10, then the digits are swapped and printed out encrypted and ready for transmission.
