Challenge Problems
Push your limits with challenges.
Question 1
Design a 2nd order Chebyshev low-pass filter with a cutoff frequency of 150 MHz. Given the normalized values from design tables: C1 = 0.5 F, L2 = 1.0 H. Provide the scaled component values for a system impedance of 100 Ohms.
💡 Hint: Make sure to apply the scaling formulas correctly.
Question 2
You want to convert a low-pass filter designed at 50 MHz into a band-pass filter with the same center frequency. List the necessary transformations for inductors and capacitors.
💡 Hint: Think of how filter types affect component roles.
