  1. Introduction to Electronics ' Voltage ' Power ratio of a filter (in decibels). ' Critical cutoff ( break, - 3dB, half- power frequenc of a filter response). ' Pass band Band reject frequencies. ' Bode plot of a filter ' filter type.
  2. FILTERS MAY BE CLASSIFIED AS EITHER DIGITAL OR Digital filters implemented using a digital computer either passive or active and are USUally implemented with R, L, and C components and operational amplifiers.
  3. (O) O Active filter Passive filter 1 04707 R,LC Ideal Actual Source like OA* No SOUrce, L may be omitted Clitical frequency I
  4. Filter responses shown in plots and specifications are often in terms of decibels, which is defined as out dB = 1010g in Another USefUl definition for the decibel, when measuring voltages across the same impedance is out dB = 2010g in
  5. Example: Low pass filter vo(jw) Vi(jw) jwc jwc 1 + j WRC
