    • FREQUENCYRESPONSE Dr. Ir. Bambang Sujanarko, M.M. Teknik Elektro Universitas Jember
    • Gain and phase changed, etc V or i CircuitFrequencyvariation
    • Transfer Function numerator denominator
    • The Decibel ScaleFrequency Response drawn using Bode plots. The Bode plots are based onlogarithms, so it is important to keep the following properties of logarithms :Gain in the Bode Plots, use Decibel scale and usually remark as GdB
    • Bode PlotsSeven types of different factors that can appear in various combinationsin a transfer function.
    • 1. Gain K
    • 2.
    • 3.w << 1/T w >> 1/T
    • 3.w << wo w >> wo w high
    • Series Resonance
    • Parallel Resonance
    • Passive FiltersLowpass Filter
    • Highpass Filter Bandpass Filter
    • Bandstop /Bandreject/ Notch Filter Active FiltersActive filters consist of combinations of resistors, capacitors, andop amps.
