1. (a) A periodic signal f(t) has a period To. Write the relationship between f(t) and To. (b) An amplitude modulated signal x(t) can be represented by x(t) = A [1 + cos (wot)]cos (wet), where A and wo are constants. (i) Show that the signal is a periodic signal. (ii) Using the definition of the period of a periodic signal, find the period of the signal. (c) Above signal x(t) can be represented as a summation of waveforms x(t) = En=0 An cos(wit) + B₂ sin(wrt). (i) Find the value of wT. (ii) Find the values of A, and B, for n = 0, 1, 2, ......, 00.

Instructor note: Important Coding Guidelines: Use comments, and whitespaces around operators and assignments. Use line breaks and indent your code. Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code. Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable. A pedometer treats walking 1 step as walking 2.5 feet. Define a method named feetToSteps that takes a double as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. Then, write a main program that reads the number of feet walked as an input, calls method feetToSteps() with the input as an argument, and outputs the number of steps. Use floating-point arithmetic to perform the conversion. Ex: If the input is: 150.5 the output is: 60 The program must define and call a method:public static int feetToSteps(double…
General Computer Accessory Company: In General Computer Accessory Company (GCAC), each product (described by product number (primary key (PK)), description, and cost) comprises at least one component and can comprise many components (described by component number (PK), description, and unit of measure), and each component is used to make zero to many products. GCAC keeps track of the quantities of products and components in the manufacturing process. In addition, a component can be used to make zero to many other components and a component can consist of zero to many other components. GCAC also keeps track of how many components go into making some other components.
