Dolphins emit sound bursts that range in frequency from 1 Hz to 120 kHz. Say that a dolphin is using a sound burst consisting of these frequencies as a form of sonar, like bats. Let the burst last for a time interval of 10 ms, after which it listens for 100 ms. Say that the logarithmic intensity (loudness) of the dolphin's sound is 50 dB as measured at 1 m away. Dolphins can hear sounds that are 2 dB below...

DC-AC inverters have many commercial and residential applications, including uninterruptible power supply (UPS) units, adjustable speed drives (ASD) for AC motors, and electronic frequency changer circuits. They are also used in solar electrical systems where batteries are charged from solar panels and used as the input DC voltage source. The inverter circuit converts the DC into AC voltage of desired frequency. Most of us are also familiar with HVDC transmission systems, where high voltages are first converted from AC to...
