Develop a CrossOver, a device to select frequency ranges and send them to the correct speaker, thus increasing its life. From Figure 1, it can be seen that each frequency range is that each frequency band is composed of a PA Filter in series with a PB Filter.
Data: Output frequency range (Hz): 3k-10k.
Note: The project should be simulated in Multisim and assembled on the protoboard to validate the results.
Expert Answer
The answer of this question is written below with detailed information and explaination To design a crossover device for selecting frequency ranges and sending them to the correct speakers, follow these steps:1. Determine the required frequency ranges: In this case, the specified frequency range is 3kHz to 10kHz.2. Choose the appropriate filter types: Based on the frequency range, select suitable filters for each band. Commonly used filter types for crossovers are Butterworth, Linkwitz-Riley, and Bessel filters. The specific filter characteristics will depend on your requirements.3. Design the PA Filter: Design a filter for the lower frequency range (3kHz to 10kHz). This filter will allow frequencies within the specified range to pass through while attenuating frequencies outside the range. Determine the filter order, cutoff frequency, and component values based on the selected filter type.4. Design the PB Filter: Design a filter for the higher frequency range (10kHz and above). Similar to the PA Filter, design this filter with the desired characteristics using the selected filter type.
