Webfunction. For the low-frequency segment (i.e., TL(s)) of the magnitude plot this will be designated by fL (or ωL =2π fL). In a practical case the function TL(s) may have several poles and zeros at low frequencies. The pole which is closest to the flat mid-band value is known as the low frequency dominant pole of the system. Thus it is the pole of highest … Web26 de mai. de 2024 · Topic: Hybrid-Pi Model of BJT.Explained High frequency model of BJT CE Amplifier also called as Expanded Hybrid pi equivalent circuit of BJT CE Configuration...
