To find the pole-zero locations of a third-order linear phase low-pass filter (LPF) and high-pass filter (HPF), follow these steps:

1. Determine the transfer function of the filter. The transfer function for a third-order LPF can be represented as H(s) = K / (s^3 + a2*s^2 + a1*s + a0), where s is the Laplace variable and K is the gain factor. For a third-order HPF, the transfer function can be represented as H(s) = K * (s^3 + a2*s^2 + a1*s + a0).

2. Set the transfer function equal to zero to find the zeros. For the LPF, set H(s) = 0 and solve for s. For the HPF, set H(s) = 0 and solve for s.

3. Set the denominator of the transfer function equal to zero to find the poles. For the LPF, set s^3 + a2*s^2 + a1*s + a0 = 0 and solve for s. For the HPF, set s^3 + a2*s^2 + a1*s + a0 = 0 and solve for s.

4. Once you have the values of s for the zeros and poles, you can plot them on the complex plane. The zeros will be represented by x marks, while the poles will be represented by o marks.

5. Analyze the locations of the zeros and poles. The LPF will have three zeros and three poles, while the HPF will also have three zeros and three poles. The locations of the zeros and poles will determine the frequency response characteristics of the filter.

By following these steps, you can determine the pole-zero locations of a third-order linear phase LPF and HPF.
