Question

Find K (the constant) for the magnitude characteristic shown in Fig. P12.31, given t1 = 2, t2 = 5, t3 = 9, and t4 = 11, using the transfer function form 

**Problem Statement:**

**Objective:** Find \( K \) (the constant) for the magnitude characteristic shown in Fig. P12.31.

**Given Data:**
- \( t1 = 2 \)
- \( t2 = 5 \)
- \( t3 = 9 \)
- \( t4 = 11 \)

**Using the Transfer Function:**
\[
H(j\omega) = \frac{K(j\omega+z_1)(j\omega+z_2)}{(j\omega+p_1)(j\omega+p_2)}
\]

**Diagram Explanation:**
- The graph is a Bode plot representing the magnitude (in dB) vs. frequency (rad/s).
- The y-axis represents magnitude in decibels (dB).
- The x-axis represents angular frequency in radians per second (rad/s).
- There are two slopes:
  - A rising slope of +20 dB/decade from \(t1\) to \(t2\).
  - A flat line from \(t2\) to \(t3\).
  - A declining slope of -20 dB/decade from \(t3\) to \(t4\).

**Magnitude Levels:**
- Starts at 0 dB, rises to 40 dB, remains constant, and then drops again to 40 dB beyond \(t4\).

**Notes on Entering Solution:**
- Enter the answer to two decimal places.
- Find \( K \) (NOTE: Not in decibels).
- Do not include units in your answer.

**Instructions:** Use the provided transfer function and graph to calculate the constant \( K \) based on the given time intervals and slopes.
