High Pass Filter is the exact opposite to the low pass filter circuit as the two components have been interchanged with the filters output signal now being taken from across the resistor. Where as the low pass filter only allowed signals to pass below its cut-off frequency point, ƒc, the passive high pass filter circuit as its name implies, only passes signals above the selected cut-off point, ƒc eliminating any low frequency signals from the waveform.

Applications of the High Pass Filter
• High Pass filters are used to reject any low-frequency components for the system
• Highpass Filters are used in radio receivers and satellite technology to attenuate low-frequency noise
• High Pass Filters are used in harmonics measurements to avoid fundamental signals from the source
• RF laboratories use highpass filters to build various test setups which require low-frequency isolation and only allow high-frequency harmonics range
