Abstract : The patent relates to a network for sensing video noise power over a wide dynamic range and outputting a voltage proportional to that noise power. The input signal is filtered, inverted and rectified to separate the noise component from the signal. The noise component is then converted to a negative level voltage which is added to first and second preset voltages. A non-linear output voltage which is a function of the first signal sum is provided for driving the voltage threshold devices in external equipment. A linear voltage output which is a function of the second signal sum is also provided for driving the voltage threshold devices of external equipment.
