+# Тест по Тест по Теме 7
+
+Соловьёва Екатерина, А-01-23
+
+## 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
