You will calculate the missing resistor or capacitor value, and sketch the resulting phasor. This exercise will help you connect theory and design, and strengthen your understanding of phasor-based circuit behaviour. I’ll give you the steps you will need to follow to solve this problem. At the end of the instructions, you’ll find the known problem parameters and the unknown you will need to calculate. Step 1: Understand the problem You are given: – The type of filter: RC Low-Pass Filter – One component value: either R or C – A target behaviour at a specified frequency, described by: – A desired magnitude (gain) – And\/or a desired phase shift Step 2: Recall the transfer function The transfer function of the RC low-pass filter is: where: – \ud835\udf14 = 2\ud835\udf0b\ud835\udc53 (angular frequency) – \ud835\udc53 is the given frequency The magnitude of the transfer function is: The phase of the transfer function is: Step 3: Set up your equations Depending on what you are asked to match (magnitude, phase, or both), set up the appropriate formula: Introduction to Electronic Filters \u25cf 138 \u2022 For magnitude: Solve for \ud835\udc45 or \ud835\udc36 using: \u2022 For phase: Solve for \ud835\udc45 or \ud835\udc36 using: Step 4: Solve for the unknown component \u2022 Rearrange your formula algebraically to isolate R or C.<\/p>\n

\u2022 Carefully substitute the given values and calculate. Step 5: Sketch the phasor \u2022 Draw a real-imaginary axis. \u2022 Draw an arrow (phasor) starting at the origin: Length (the calculated magnitude) and Angle (the calculated phase shift relative to real axis) Step 6: (optional) verification \u2022 You may check your answer by simulating the circuit in CircuitLab or another simulator. \u2022 Measure the output magnitude and phase at the specified frequency.<\/p>\n

\u2022 Confirm if your design meets the target. ### Practice Problem 1 Given: \u2022 \ud835\udc36 = 1 \ud835\udf07F \u2022 Desired behaviour at \ud835\udc53 = 159 Hz: o Magnitude \u2248 0.707 o Phase \u2248 -45\u00b0 Task: Calculate the required resistor value \ud835\udc45.<\/p>\n
