Detailed Solution
Download Solution PDFThe correct option is 4
Concept:
1) Low pass filter - This allows signals with a frequency lower than a certain cutoff frequency to pass through but reduces the amplitude of frequencies higher than the cutoff frequency. This doesn't exactly match the characteristics of a wave trap.
2) High pass filter - This type of filter does the opposite of a low pass filter. It allows signals with a frequency higher than a certain cutoff frequency to pass through and attenuates frequencies below that. It's also not the best description of a wave trap.
3) Wideband amplifier - This device amplifies a wide band of frequencies. It doesn't seem to avoid a certain frequency like a wave trap would.
4) Resonance circuit - This type of circuit responds strongly to a specific frequency and less so to others. It can be designed to either favor or reject a certain frequency. A wave trap is essentially a type of resonant circuit that's tuned to a frequency that it 'traps' or blocks, hence preventing the frequency from passing through the circuit.
