- Give the input and output impedances for an ideal-voltage amplifier. Repeat for each of the other ideal amplifier types.arrow_forwardInput signals that have high voltage noise that must be filtered cannot be immediately buffered because the buffer power supply voltages are often lower than the voltages present in the noise. With this in mind there are two circuits we have demonstrated that can work in this scenario. If you have a high impedance source, is it better to use an RC lowpass filter followed by a non-inverting amplifier, or to use an active lowpass filter design (both pictured below) and why?arrow_forwardThe partial gain for Vg is -2 ±10% R2 = 1kΩ. R1 = 10kΩ Rf = 2kΩ. Record the amplitude of the signal source (vg), the ac component of the output (vout), and the dc component of the output (VOUT) in Table 3. Test to see whether you have met your design criteria. The measurements that you made in Table 3 should assist you in this. Show the results of your comparisons in Table 4.arrow_forward
