The digital control circuit provides a digital control signal to the SLIC device in response to a sample digital control signal and the digital parameter signal.

In response to the received signal the digital controller generates a digital control signal and powers a lamp through the output stage according to the generated digital control signal.

The PI controller generates a digital control signal which is used to control a valve in the digital mass flow controller.

The analog control signal is obtained from the digital control signal by a D/A converter (6).

Further, the pre-processor derives one or more digital control values of a second digital control signal communicated over the transmission channel without ever being compressed, directly to the digitally-controlled post-processor.

Preferably, the digital parameter signal relates to a sensed current signal and the sample digital control signal relates to a desired voltage signal.

The digital control signal may be encoded in the analog data signal by a digital shift in the DC bias level or by a complete removal of the DC biasing signal.

A pre-emphasis digital circuit (36) receives a digital magnetic field gradient control signal and outputs pre-emphasis correction terms.

A high frequency injection system overlays a textured signal onto a digital control signal for controlling motion base.

The invention relates to a data transfer system for transmitting a digital control signal (SSt) or the feedback signal (SRSt) thereof.

Said amplifier can operate as a normal amplifier or as a buffer according to a digital control signal.

Disclosed are a system and a method for transmitting video signal and data signal in a CCTV, which can save installation costs by transmitting video signal and data signal through a single coaxial cable and minimize distortion of video.

A control circuit (107) produces data ready signal (32) on the conversion done signal and causes the serial interface circuit to serially shift the bits in response to a digital control signal (SCLK).
