Q1: The frequency response of a microphone meansA
bandwidth of frequencies having output with in ± 1 dB of the output at 1000 Hz
B
bandwidth of frequencies having output with in ± 3 dB of the output at 1000 Hz
C
bandwidth of frequencies having output with in ± 1 dB of the output at 500 Hz
D
bandwidth of frequencies having output with in ± 3 dB of the output at 500 Hz
ANS:A - bandwidth of frequencies having output with in ± 1 dB of the output at 1000 Hz 100 Hz is taken as standard for specifying the output. |
