Low Pass Filters
Zo = characteristic impedance in ohms
C = Capacitance in Farads
L = Inductance in Henries
Fc = Cutoff frequency in Hertz
High pass filters
Zo = characteristic impedance in ohms
C = Capacitance in Farads
L = Inductance in Henries
Fc = Cutoff frequency in Hertz
Band Pass Filters
Zo = characteristic impedance in ohms
C1 and C2 = Capacitance in Farads
L1 and L2 = Inductance in Henries
f1 and f2 = Cut off frequencies in Hertz
Band Stop Filters
A Band stop of Frequency Rejection Filter
Used to stop certain frequencies for example 2m where there is interference on a television set.
Braid Breaker Filter
A 1-1 Braid Breaker
A UHF Braid Breaker
Used to insulate Television antennas where there are EMC Issues
