filter passband การใช้

• For example, widening of current filter passband requires approximately proportional increment of all the coupling coefficients k _ { i, i + 1 }.
• Consequently, the desired harmonic mixer output ( representing the difference between the " N " harmonic and the VCO output ) falls within the loop filter passband.
• In electronic filter design, a filter specification may require that within the filter passband, the gain is nominally 0 dB ?a small number of dB, for example within the ? dB interval.
• In this way, the filter passband can be narrowed so that each color component lets only a very narrow band of spectrum through the LCD . This improves the efficiency of the display since less light is blocked when white is displayed.
