Step 1
The circuit consists of a resistor (R) and a capacitor (C) in series at the input, and a feedback resistor (Rf) from the output to the inverting input of the op-amp. The cutoff frequency (fc) of the high-pass filter is given by the formula: fc = 1/(2πRC) Given Show more…

HWZ: a) Using 0.1 μF capacitors, design an active broadband first-order bandpass filter that has a lower cutoff frequency of 200 Hz, an upper cutoff frequency of 2000 Hz, and a passband gain of 0 dB. b) Write the transfer function for the scaled filter. c) Use the transfer function derived in part (b) to find H(jωo) where ωo is the center frequency of the filter. d) What is the passband gain (in decibels) of the filter at ωo?

Determine the cutoff frequency of the lowpass filter described by $$\mathbf{H}(\omega)=\frac{4}{2+j \omega 10}$$ Find the gain in $\mathrm{dB}$ and phase of $\mathbf{H}(\omega)$ at $\omega=2$ $\operatorname{rad} / \mathrm{s}$.
