I need proper solution for the following( underdstandable writing and well explained) thank you  What is resonance in LCR circuit? and tell the difference between impedance and resistance?

Sketch the Vout/Vin versus frequency characteristics of an LC Bandpass filter. Show flc and fhc on the sketch and explain how they are defined. On this sketch, show the bandwidth (BW) of the filter and explain how it is defined.

(b) High-frequency ECG biopotentials analysis in the ST-T segment of a high-resolution ECG signal recording requires the analysis of signal components above 30 Ilz and below 800 Hz. Design a first order band pass passive filter to accommodate this specified frequency bandwidth. Sketch the circuit configuration. You may use an op- amp buffer stage in your circuit design.

CR active filters find extensive use in communications and instrumentationmeasurements.a) By considering how the capacitor impedance in Figure 1 varies with frequency,explain if the circuit in Figure 1 acts as a low-pass or high-pass filter.b) Derive the closed-loop gain for the case of very high frequencies.c) Draw a graph that shows the frequency response of the CR active high-passfilter. The y-axis should correspond to gain in dBs and the x-axis to frequency.Make sure that you clearly indicate the 3 dB point and the equation thatdescribes the relationship between ω and CinRin at the cut-off frequency.
