Consider the following statements:1) Two identical 2nd order Butterworth LP filters when connected in cascade will make a 4th order Butterworth LP filter.2) A high 2nd order filter will exhibit a peak if Q exceeds a certain value.3) A bandpass filter cannot be of order one.4) A network consists of an amplifier of real gain A and a β network in cascade with each other. The network will generate sinusoidal oscillations if the β network is a first-order LP filter.Which of the above statements are correct?
