What is a passband ripple?
Passband Ripple and Stopband Attenuation. In many applications, you can allow the gain in the passband to vary slightly from unity. This variation in the passband is the passband ripple, or the difference between the actual gain and the desired gain of unity.
What is passband and stopband ripple?
Passband ripple occurs in the high-gain region of a higher-order filter or amplifier's transfer function, and looks like some variations in the output gain. The same applies to the phase on the output. In effect, the two are not smooth functions of frequency. Ripple can also appear in the stopband in these circuits.
Which filter has ripple in passband?
Chebyshev Filter: It is also called an equal ripple filter. It gives a sharper cut-off than Butterworth filter in the passband. It has a ripple response in the passband and flat response in the stopband.
What is the value of passband ripple?
What is the value of pass band ripple in dB? Explanation: 1-δP is known as the pass band ripple or the pass band attenuation, and its value in dB is given as -20log(1-δP).
