🔍 Key Concepts

• Relationship between RC networks and their effect on specific frequency ranges • How a Twin-T (or bridged-T) network behaves at its center (notch or resonant) frequency • Difference in response shape between low-pass / high-pass filters and band-pass / notch filters

💭 Think About

• Look at how many resistors and capacitors are used in section C and how they are connected between input, ground, and the amplifier input. Does this look like a simple one-pole RC, or something more complex aimed at one particular frequency? • Ask yourself: at the design frequency fn = 1 / (2πRC), does this network tend to strongly pass that frequency, or strongly cancel it? How would the output behave at frequencies well below and well above fn? • Compare circuit C with circuits A and B. Since A and B are classic low-pass and high-pass active filters, what different job is circuit C doing in a typical filter set?

✅ Before You Answer

• Identify whether the RC network in C is arranged so that signals at one specific frequency are either maximized or minimized. • Confirm if the response around fn is very narrow (selective) as opposed to gradually rolling off like a simple low-pass or high-pass. • Decide whether this circuit would be used when you want to isolate a narrow band of frequencies or reject a narrow band while passing those above and below.
