The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?

Answers

Answer 1

Answer:

P₂ = 0.5 W

Explanation:

It is given that,

The attenuation of a signal is -10 dB.

We need to find the final signal power if it was originally  5 W.

Using attenuation for signal :

[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]

Put dB = -10, P₁ = 5 W

Put all the values,

[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]

So, the final signal power is 0.5 W.

Answer 2

The final signal power if it was originally 5W is; 0.5 W

Signal Power

We are given;

Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 W

Formula for attenuation signal is;

dB = 10log_10_ (P2/P1)

Where P2 is final signal power

Thus;

-10 = 10log_10_(P2/5)

-10/-10 = log_10_(P2/5)

-1 = log_10_(P2/5)

0.1 = P2/5

P2 = 0.1 × 5

P2 = 0.5 W

I am having trouble with doing this code on Python:Develop the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.Ex: If the input is:2011 18000 2018where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770Note: print_info() should use three spaces for indentation.

Answers

Answer:

class Car:

   def __init__(self, model_year, purchase_price):

       self.model_year = model_year

       self.purchase_price = purchase_price

       self.current_year = 0

       self.current_value = 0

   def set_current_year(self, year):

       self.current_year = year

   def calc_current_value(self, current_year):

       if self.current_year == 0:

           return "Must first input the current year"

       depreciation_rate = 0.15

       car_age = current_year - self.model_year

       self.current_value = round(self.purchase_price - (car_age * (self.purchase_price * 0.15)))

   def print_info(self):

       print("Car's information:")

       print(f"Model year: {self.model_year}")

       print(f"Purchase price: {self.purchase_price}")

       if self.current_value > 0:

           print(f"Current value: {self.current_value}")

       else:

           print("Current value: Unknown")

Explanation:

The python program above defines the class "Car" that accepts the model year and purchase price of an instance. The class has a set method for the current year variable that is used to calculate and update the current value variable of the object. The print_info method prints the car model year, purchase price and its current value after nth years.
