Some Important Questions about Different Frequency Bands
Q. What is -3dB frequency response or -3dB bandwidth?
A. At the circuit level, the phrase 3dB frequency response is frequently used. In short, a -3dB frequency response indicates that the signal's power has decreased to half of what it was initially. The frequency at which the output gain is lowered to 70.71% of its highest value is defined by these -3dB corner frequency points. Then, we can rightly state that the frequency at which the system gain has decreased to 0.707 of its maximum value is at the -3dB point. [Read More]
