STC networks can be classified into two categories: low-pass (LP) and high-pass (HP). Then which of the following is true?
- a)HP network passes dc and low frequencies and attenuate high frequency and opposite for LP network
- b)LP network passes dc and low frequencies and attenuate high frequency and opposite for HP network
- c)HP network passes dc and high frequencies and attenuate low frequency and opposite for LP network
- d)LP network passes low frequencies only and attenuate high frequency and opposite for HP network
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
STC networks can be classified into two categories: low-pass (LP) and ...
By definition a LP network allows dc current (or low frequency current) and an LP network does the opposite, that is, allows high frequency ac current.

Understanding Low-Pass and High-Pass Networks
Low-pass (LP) and high-pass (HP) networks are essential components in electrical engineering, particularly in signal processing. They are distinguished by their frequency response characteristics.
Low-Pass (LP) Networks
- Functionality: LP networks are designed to allow low frequencies to pass through while attenuating higher frequencies.
- DC Response: They pass direct current (DC) and low-frequency signals effectively.
- Frequency Attenuation: As the frequency increases beyond a certain cutoff point, the LP network reduces the signal amplitude significantly.
High-Pass (HP) Networks
- Functionality: HP networks do the opposite; they allow high frequencies to pass while attenuating low frequencies.
- DC Response: HP networks block DC (zero frequency) and low-frequency signals.
- Frequency Attenuation: Signals with frequencies below a specific cutoff frequency are significantly reduced in amplitude.
Explanation of Option B
- Correct Statement: Option B accurately states that LP networks pass DC and low frequencies while attenuating high frequencies, and the opposite holds true for HP networks.
- Comparison: This characterization aligns with the basic definitions of LP and HP filters in electrical engineering.
Conclusion
Understanding these characteristics is crucial for designing circuits that meet specific frequency requirements, ensuring optimal signal processing in various applications.
