Calculate impedance of a series circuit containing resistor, inductor and capacitor at specific frequency
At 1kHz frequency, the inductive reactance is approximately 62.8Ω, and capacitive reactance is approximately 159.2Ω. Since capacitive reactance is greater than inductive reactance, the circuit exhibits capacitive characteristics.
Design PCB trace width calculation for 50Ω characteristic impedance
For standard FR4 substrate, to achieve 50Ω characteristic impedance, the trace width needs to be approximately 2.7mm. This is the standard impedance value for high-frequency signal transmission.
Analyze capacitor impedance variation across different frequencies
Capacitor impedance is inversely proportional to frequency. When frequency increases by 10 times, impedance decreases by 10 times. This is the fundamental working principle of capacitors in filter circuits.
Calculate resonant frequency and impedance characteristics of LC parallel circuit
At resonant frequency, LC parallel circuit exhibits maximum impedance. Higher Q factor results in better selectivity and narrower bandwidth.
