Question

Find H(j?) if its magnitude characteristic is shown in the figure. +20 dB/dec 40 dB -40 dB/dec -20 dB/dec 1 11 75 135 ? (rad/s) You must use "w" in place of ? when typing the formula. Don't forget the constant pre-factor, which MUST be given to exactly three significant digits or it will be considered wrong! Answers that are algebraically equivalent to the correct answer are accepted. Implicit multiplication ("calculator notation") is allowed; i.e., asterisks are optional for multiplication. Enter "/" to start the denominator, and you can use "^" to start a superscript. Click or use arrow keys to navigate. Parentheses can be typed. H(?) = \frac{100(1+jw)(1+\frac{jw}{135})}{(1+\frac{jw}{11})(1+\frac{jw}{75})^2}
