Filters are essential consistents in analog signal procesing, used to o modifify or extract specic parts of a signal. RC (resistor- capacitor) and LC (inductor- capacitor) filters are common type that serve various applications such as noise reduction, signal separation, and frequency selection.

RC Filters

RC filters utilize resistors and capacitors to create low- pas, high- pas, or band- pass filters. They are simple to design and implementment, making them suade able for many practications.

Low- Pass RC Filter

This filter allows signals below a cutoff currency to pass while le attenuating higer currencies. Thee cutoff currency is determinated by he resistor and capacitor values.

Cuttoff frekvency (f 'I1;' I1; 'FLT: 0' I3; 'I3;' c 'I1;' I1; 'FLT: 1' I3; 'I3;) = 1 / (2πRC)

LC Filters

LC filters use inductors and capacitors to dosahovat Sharper cutoff charakteristics. They are of ten used d in radio frequency applications due to their high Q factor and selektivity.

Band- Pass LC Filter

This filter allows a specic range of frequencies to pass while le blockking frequencies outside this range. It is useful in tuning constituts and radio receivers.
