the old solution is wrong, solve it in detail Design a sinusoidal oscillator circuit whose oscillation frequency can be changed between 1kHz and 20kHz. The supply voltage of the circuit will be 7.4V single supply. Design the supply voltage circuit yourself. Only AC voltage can be taken from the experiment table. Then apply the output of the oscillator circuit you designed to the second-order low-pass active filter. Design the appropriate filter circuit so that the cut-off frequency of the filter is 10kHz. The supply voltage of the filter circuit is also 7.4V. By observing the output signal of the oscillator circuit on the oscilloscope, test whether it works stably at the desired frequencies and record the measurement results. Interpret the results in the report section of the experiment. Obtain the variation of the output of the filter circuit with frequency. Determine the cutoff frequency. Interpret the results.
