For a gain constant K, the phase-lead compensator

1. reduces the slope of the magnitude curve in the entire range of frequency domain
2. decreases the gain cross-over frequency
3. reduce the phase margin
4. reduce the resonance peak M_p

Lead compensator increases the gain-crossover frequency. It also increases the phase margin. The high frequency

end of the log magnitude plot has been raised by a dB gain of 20 log (	1	).
