A Compact Lowpass Filter for Satellite Communication Systems Based on Transfer Function AnalysisThis paper presents a very efficient design procedure for a high-performance microstrip lowpass filter (LPF). Unlike many other sophisticated design methodologies of microstrip LPFs, which contain complicated ...

Kis the filter gain. Tis the filter time constant. Tsis the filter sample time. From the discrete transfer function, the filter equations are defined using the forward Euler method: ⎧⎪⎨⎪⎩x(n+1)y(n)=(1−TsT)x(n)+K(TsT)u(n)=x(n) y(0)=x(0)=Ku0, ...
The effect of zero insertion is illustrated in Figure 7.5, where the magnitude function ∣H0(ejω)∣ of an ideal highpass filter is shown together with the function ∣H(ejω)∣ resulting from setting D = 5. The D-fold repetition of the filter transfer function attenuates not only the ...
Ts is the filter sample time. From the discrete transfer function, the filter equations are defined using the forward Euler method: ⎧⎪⎨⎪⎩x(n+1)y(n)=(1−TsT)x(n)+K(TsT)u(n)=x(n) y(0)=x(0)=Ku0, where: u is the filter input. x is the filter state...
A low-pass filter, which is implemented with a Sallen–Key topology, withfc=15.9 kHz andQ= 0.5 这个电路是一个单位增益的电路,改变Sallen-Key 滤波器的增益同时就改变了滤波器的幅频特性和类型。 实际上Sallen-Key 滤波器就是增益为1的Butterworth 滤波器。
