|
## Задание
|
|
|
|
Разработайте функцию с 3 аргументами: x, А и В, реализующую преобразование входного сигнала x по формуле:
|
|
y=B, если x>A;
|
|
y= 2B*x/A-B*x^2/A^2 , если 0≤ x ≤ А;
|
|
y= 2B * x/A +B*x^2 /A^2 , если -A≤ x <0;
|
|
y=-B, если x< -A.
|
|
Создайте список со 100 значениями входного сигнала х – случайными, равномерно распределенными числами в диапазоне значений от -5 до 12. Для элементов списка с помощью функции рассчитайте список со значениями выходного сигнала y при трех разных парах значений А и В. Записать результаты в текстовый файл в виде двух столбцов: хi, yi.
|
|
|
|
## Решение
|
|
|
|
```py
|
|
import random
|
|
|
|
def func(x, A, B):
|
|
if x > A:
|
|
return B
|
|
elif 0 <= x <= A:
|
|
return (2 * B * x / A) - (B * x**2 / A**2)
|
|
elif -A <= x < 0:
|
|
return (2 * B * x / A) + (B * x**2 / A**2)
|
|
else:
|
|
return -B
|
|
|
|
x_values = [random.uniform(-5, 12) for _ in range(100)]
|
|
|
|
params = [(5, 7), (3, 4), (8, 12)]
|
|
|
|
with open('test.txt', 'w', encoding='utf-8') as f:
|
|
for A, B in params:
|
|
f.write(f'\nПараметры: A = {A}, B = {B}\n')
|
|
f.write('xi yi\n')
|
|
f.write('----------------\n')
|
|
|
|
for x in x_values:
|
|
y = func(x, A, B)
|
|
f.write(f'{x:10.5f} {y:10.5f}\n')
|
|
```
|
|
|
|
## Вывод
|
|
```txt
|
|
Параметры: A = 5, B = 7
|
|
