What is the cut-off frequency in an R-C circuit?
💡 Hint: Remember the typical definition of cut-off frequencies in filters.
True or False: The phase shift in an R-C circuit decreases from 0° to -90° as frequency increases.

Challenge Problems
Push your limits with advanced challenges
Design an R-C low-pass filter with a cut-off frequency of 1 kHz. Choose appropriate values for R and C.
💡 Hint: Ensure you select standard component values that are easily available.
Analyze the phase shift of an R-C circuit at three distinct frequencies: lower than the cut-off, at the cut-off, and higher than the cut-off.
💡 Hint: Sketch the phase response to visualize clearly how shifts occur.
