Final answer:

Create a Simulink model with a high-pass and low-pass filter to simulate a band pass filter, using the specified time constants to set up both filters. Analyze the output using a spectrum analyzer to determine the frequencies passed by the filter. Record the data and submit reports as instructed.

Step-by-step explanation:

To solve the band pass filter equation using MATLAB and Simulink, you first need to create a model in Simulink that consists of a high-pass filter (HPF) block and a low-pass filter (LPF) block in series to represent the band pass filter. The given time constants will define the cutoff frequencies for each filter.

For the HPF, with a time constant of 9.23 nanoseconds, the cutoff frequency (ωc) is given by ωc = 1/(RC), where R is the resistance and C is the capacitance. To find R or C, one of them needs to be predefined. Similar calculations apply for the LPF with a time constant of 8.16 microseconds.

After creating the simulink model, you can use a spectrum analyzer block to perform an FFT analysis of the output signal. This will allow you to observe the frequency components of the signal passed by the band pass filter.

To interpret the results, look at the spectrum analyzer output. The filter should attenuate frequencies outside the band defined by the cutoff frequencies of the HPF and LPF. Finally, record the data by plotting the output signal and its spectrum.

Remember to work in a group if required and submit the reports as per your assignment instructions.
