Up-down counter

In digital logic and computing, a counter is a device that stores (and sometimes displays) the number of times a particular event or process has occurred, often in relationship to a clock. A sequential digital logic circuit is the most common type with an input line or clock and multiple output lines. In the binary or binary-coded decimal (BCD) number system, the values on the input line represents a number by several flip-flops connected in a cascaded manner. They are manufactured as separate integrated circuits and are widely used components in digital circuits. These are also a part of larger integrated circuits. These are a specific type of sequential circuit like registers or the value of the flip-flops serving as the output.

Question

### Square Wave Analysis

#### Description

The image illustrates a square wave function, denoted as \( f(t) \). The graph shows the square wave alternating between two levels, with a period \( T \) and symmetrical intervals of \( \frac{T}{2} \).

#### Graph Explanation

- **Time Axis (\( t \))**: The horizontal axis represents time.
- **Signal Value (\( f(t) \))**: The vertical axis represents the amplitude of the signal.
- The square wave is shown oscillating between two levels at intervals of \( \frac{T}{2} \).

#### Tasks

1. **Find \( DC \) (Direct Current Component)**
- Determine the average value of the function over one period.

2. **Find \( a_n \) (Fourier Cosine Coefficients)**
- Calculate the coefficients for the cosine terms in the Fourier series expansion.

3. **Find \( b_n \) (Fourier Sine Coefficients)**
- Calculate the coefficients for the sine terms in the Fourier series expansion.

#### Note on Fourier Series

The function \( f(t) \) can be expressed as a Fourier series:

\[
f(t) = DC + \sum_{n=1}^{\infty} a_n \cos \left(\frac{2\pi n}{T} t \right) + \sum_{n=1}^{\infty} b_n \sin \left(\frac{2\pi n}{T} t \right)
\]

This series represents the square wave as an infinite sum of sine and cosine functions with varying amplitudes \( a_n \) and \( b_n \).
