One of the main issues was its narrow bandwidth due to the cut-off frequency characteristic. Later‚ researchers try to find components that could provide greater bandwidth and possible miniaturization‚ and therefore they examined

Alternating Current RC and LRC Circuits Lab 7 November 12‚ 1012 109989- 5:30 PM Abstract Within this experiment we recorded that the theoretical capacitance of 0.470 is accurate with the capacitor from box C. The LRC circuit is proven to have a voltage accurate with the measured generator voltage because the largest percentage of error ‚ 0.55 % error‚ is much lower than 5% error. Summary The idea of the alternating current RC and LRC circuits lab is to record the value
