The polar diagram displays the directional characteristic related to the measurement frequency of the microphone.

A holder kit for directional condenser microphone for improving a directional characteristic is disclosed.

A multi-frequency transmission/reception apparatus capable of obtaining arbitrary direction characteristic independently of the frequency.

A seismic directional sensor for terrestrial sound has at least one geophone with a pronounced directional characteristic.

It uses directional characteristic from the best of two worlds - both cardioid and supercardioid patterns.

Thereby, the shape of the radiation pattern of the antenna can be made more ideal and the degradation of the directional characteristic of the antenna can be prevented.

This directional characteristic offers the best of two worlds — from cardioid and supercardioid patterns.

A handheld pointer device provides radiation with a directional characteristic relative to its main axis.

According to the invention, the receivers that are addressed via the network comprise at least two antennae that are located at a distance and have predefined alignment characteristics and/or sensitivities.

Due to its narrow directional features, the microphone focuses on the main source of sound - the vocals - and the accompanying instrument is no longer heard much in the microphone.

To this end, the invention provides that a monopulse antenna is used whose directional characteristic is adaptively designed electronically or with regard to software.

The KMS 104 and the KMS 104 plus have a condenser microphone capsule with a cardioid directional characteristic which provides the best possible suppression of sounds originating from behind the microphone.

The KMS 104 has a condenser microphone capsule with a cardioid directional characteristic which provides the best possible suppression of sounds originating from behind the microphone.

The KMS 104 has a microphone capsule with a cardioid directional characteristic which provides the best possible suppression of sounds originating from behind the microphone.

In one example, an ALF classification that indicates a particular directional characteristic of a video block may be used to determine how and whether an SAO filter process is applied to each sample within the video block.
