A headphone (K) is provided with an active noise compensation unit (ASK) for the compensation of interfering noise.

The aim of the invention is to eliminate said disturbing noise by using a capacitor.

The interpolated estimate can then be used to attenuate or remove the unwanted sound.

An unwanted noise in the signal is visible in the spectrogram and the portion of the signal containing the unwanted noise can be selected using time and frequency constraints.

The clocking system also employs a noise suppression circuit for reducing spurious noise into the ATM network.

The method provides a means of reducing the confounding effect of spurious noise signals and enhancing signal to noise.

A system (10) for providing an accurate prediction of a signal-to-interference noise ratio.

Therefore, the noise of the power-supply system is little.

The vector multiplier adjusts the phase and amplitude of noise (i.e., spurious in-band noise) measured by the second receiver.

However, a GCC with a few number of levels introduces noise in a picture.

Two banks of oscillators (10) (20) are selectively mixed to yield a range of output signals of low phase noise and low spurious noise.

Used with a Takamine, absolutely no hiss nor parasite is heard.

The Arbiter is equipped with our passive EMI / RFI filter.

The noise signals are combined with the analog signals before the input to the A/D converter (435), where the combintation of the signals reduces the spurious noise signals.

Requires a quiet room without noise to give good results.
