The Challenge:

Let's jump straight into a challenging filter design assignment question that many students find perplexing:

Question:

Design a low-pass Butterworth filter with a cutoff frequency of 1 kHz and a gain of 2. Explain the design parameters and justify your choices.

Understanding the Concept:

Before we delve into the step-by-step solution, let's grasp the fundamental concepts involved in this question.

Low-pass Butterworth Filter:

A low-pass Butterworth filter allows low-frequency signals to pass through while attenuating higher frequencies. The Butterworth filter is known for its maximally flat frequency response within its passband.

Cutoff Frequency:

The cutoff frequency is the point at which the filter's output amplitude is reduced to 70.7% (or -3 dB) of its maximum value.

Gain:

The gain of a filter is the ratio of the output amplitude to the input amplitude. In this case, we are tasked with designing a filter with a gain of 2.

Step-by-Step Guide:

1. Define Specifications:

Clearly define the specifications of the filter, including the cutoff frequency (1 kHz) and the gain (2).

2. Choose Filter Type:

Select a Butterworth filter for its smooth frequency response. Butterworth filters are often preferred when a maximally flat passband is desired.

3. Determine Order of the Filter:

The order of a filter determines its roll-off rate and is crucial for achieving the desired characteristics. In this case, choose an order that balances the sharpness of the roll-off with the complexity of implementation.

4. Calculate Components:

Use standard formulas or online tools to calculate the component values for the chosen filter order. Components include resistors and capacitors in analog filters, or coefficients in digital filters.

5. Construct Circuit or Implement Digital Filter:

Create the filter circuit based on the calculated component values or implement the digital filter in software. Simulate the filter response to ensure it meets the specifications.

6. Justify Choices:

Explain why you chose the specific filter type, order, and component values. Justification is key to showcasing your understanding of filter design principles.
