The signal processor applies a second demodulation signal to the signal responsive to the detector output signal to generate a second output signal responsive to the second parametric signal.

The magnitude of the added noise signal is varied, and a function of the signal quality of the data signal received is determined as a function of the added noise signal.

Stimulating signal parameters of the stimulating signal are adjusted based on the feedback signal.

Power supplied to the duty cycle signal generation unit is interrupted based on the control signal and power is re-supplied to the duty cycle signal generation unit based on the wake-up signal.

An elimination error signal is generated in accordance with an echo signal and the pseudo-echo signal.

The input signal F(k) being a function of the data signal (bk), the modulation function h(t-kT) is a Gaussian function of the time t.

The control signal provided to the drive means is a function of the feedback signal.

The bandpass filter generates a filtered signal as a function of the amplified signal.

The scaler adjusts the peaking signal based upon the throttle signal.

In fact, if φ changes as a function of signal intensity, then orientation to the signal is the only stable outcome.

The input buffer generates a first signal from the input signal by adjusting a parameter of the input signal in accordance with the control signal.

The converter (24) provides the output signal as a function of the converter temperature signal, the first correction signal and the combined signal.

The duty cycle of the switching signal is adjusted based on the correction signal.

According to the signal, a withdrawing signal of the use limit is output.

The scaling function is a function of at least one of the input signal, the estimate of the first component of the input signal, the estimate of the second component of the input signal, or a residual signal.
