stopband attenuation , also: stopband atten

The stopband attenuation of the filter is also within the required specification.

The inner sections of the filter are most commonly chosen to be constant k since these produce the greatest stopband attenuation.

The parameter ε is thus related to the stopband attenuation γ in decibels by:

The number of rows of teeth down the length of the waveguide primarily affects the stopband attenuation.

Doing bit-flipping on the LSB gave 25dB improvement in terms of the stopband attenuation.

In particular, there is little stopband attenuation of TE and TE modes.

However, it is not possible to achieve both equiripple group delay and equiripple maximum stopband attenuation [7].

For a fixed stopband attenuation, the SDR can be improved by increasing the number of filter coefficients to affect a decrease in the transition band width.

The lower the value of m, the faster the transition, while at the same time, the stopband attenuation becomes less, increasing the need to use extra k-type sections as well.

After clicking "OK" button, you will see the list of filter coefficients, parameters of the designed filter, ie. achieved stopband attenuation, passband ripples and transition band.

You can specify stopband attenuation 'A'as well as the transition band 'TB' (symmetric around frequency 0.25) in the Parameters dialog (open it from the File menu).

For example for the lowpass filter design the coefficients have to be designed to decreasing the passband ripples and increase the stopband attenuation by the amplitude of the estimated quantization noise.

A stopband is a band of frequencies, between specified limits, through which a circuit, such as a filter or telephone circuit, does not allow signals to pass, or the attenuation is above the required stopband attenuation level.

Because the coefficients of digital filters are definite, they can be used to achieve much more complex and selective designs - specifically with digital filters, one can achieve a lower passband ripple, faster transition, and higher stopband attenuation than is practical with analog filters.
