FIR High-pass Filter Component

Note: The number of signal pins is variable and set in the component's Type Property.

Input Pins

Channels

Audio signal pins are represented by a () circle, and traditional wiring is represented by a thin black line. You can use Signal Names on audio signal pins.

By default, the FIR High-Pass Filter component is set to a Mono channel, which provides one input and one output. Additionally, you can set the Properties to allow for Stereo, which gives you two inputs and outputs; or you can choose Multi-Channel, which will allow you to choose between 2 and 256 inputs and outputs.

FIR High-Pass Filter Properties

Transition Bandwidth

Sets the bandwidth of the transition between the stopped frequencies and the passed frequencies.

Stopband Attenuation

Sets the attenuation level for the frequencies that are not passed.

Phase Response

Linear Phase - The delay is the same for all frequencies.

Minimum Phase - There is a minimal delay that varies with frequency.

Channels

Type

Sets the type of Channel available for Inputs and Outputs.

Count

Only appears when choosing Multi-Channel as the Type. Sets the number of Channels for Multi-channel. You can choose between 2 and 256.

Response Panel

Enabled

Determines if the Response Panel is visible in the Control Panel

Size

Determines the size of the Response Panel.

Note: When controls are changed on a design in Run mode, the output is muted (approximately 1 second) while the new coefficient set is loaded.

Response Graph

The scales for the Response Graph vary depending on the measurement method you select.

The vertical line of the crosshair cursor provides a readout of its position on the X axis scale.

The vertical movement of the horizontal crosshair follows the magnitude or amplitude of the signal.

Phase

The phase difference between the output of the filter and its input.

Bypass

Bypasses the filter.

Invert

Inverts the output signal.

Mute

Mutes the output signal.

Gain (dB)

Sets the output Gain.

Frequency (Hz) 

Sets the frequency at which the gain of the output reaches a point 3 dB below the maximum as set by the Gain control. Frequencies below this frequency are attenuated. All frequencies above this frequency are amplified based on the setting of the Gain control.

Group Delay

The time it takes for an audio signal to travel through the filter.

The available Control Pins depend on settings in Properties.
