DRDO Anti-Radiation Missile by the Indian government In February 2016, it was reported that captive flight trials of anti-radiation missile are planned for April–May this year, and the maiden flight test by year–end by the missile technologists of the DRDO. According to DRDO sources, scientists will evaluate the performance of the seeker, navigation and control system, structural capability and aerodynamic vibrations during the captive flight trials. These will be followed by ground testing and the missile will be fired from Sukhoi Su-30MKI during the actual flight trial by year-end. The missile will be inducted in about two years after conducting a number of
A/B Sound System A/B Sound System An A/B Sound System is a type of Sound reinforcement system or Public address system. Unlike a more typical sound reinforcement system, an A/B Sound System provides two electrically isolated signal paths from microphone to speaker, resulting in a system where signals from two microphones only interact acoustically and never interact electronically. This is accomplished by placing two separate loudspeakers at each speaker position and feeding the two speakers separate signals from separate microphones. The purported benefit of such a system is a reduction in phase cancellation and intermodulation distortion, and an improvement in speech intelligibility when
