What term refers to frequency-sensitive filter circuits designed to pass a certain range of frequencies from the generator to the load device and reject all other frequencies?

What term refers to frequency-sensitive filter circuits designed to pass a certain range of frequencies from the generator to the load device and reject all other frequencies?

• A. High-pass
• B. Filtering
• C. Low-pass
• D. Demodulation

Answer: (B)

The concept being tested is how circuits shape a spectrum by allowing a specific range of frequencies to pass while rejecting others. This is what filtering does—the network is designed to pass a defined band of frequencies from the generator to the load and attenuate everything outside that band. High-pass and low-pass are specific filter types that pass only frequencies above or below a cutoff, respectively, so they don’t describe passing a defined range. Demodulation is about extracting information from a modulated signal, not about selecting a frequency band. So the best fit for the described function is filtering.
