1.	Half power bandwidth is also called ______(a) Absolute bandwidth(b) Null to null bandwidth(c) 3 dB bandwidth(d) Zero dB bandwidthThis question was posed to me by my school principal while I was bunking the class.My query is from Digital Modulation in section Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» Correct OPTION is (c) 3 DB bandwidth Explanation: Half POWER bandwidth is ALSO called the 3 dB bandwidth. It is defined as the INTERVAL between frequencies at which the PSD has dropped to half power, or 3 dB below the peak value.
