A method and apparatus is provided for resetting an electronic device in response to a voltage transient. The apparatus implements the method steps of detecting the transient at an input to, and receiving an output from, a voltage sensing circuit in response to the transient. The method also includes the step of providing an electronic device reset signal at the output of the voltage sensing device by clamping the input of the voltage sensing circuit to the output of the voltage sensing circuit through an interconnected positive feedback clamping capacitor. Timing capacitors are used to extend the duration of the reset pulse.

Method of detecting voltage transients

A method is provided of attenuating a signal value within erroneous frames of a logarithmically coded digital signal. The method includes the steps of detecting an erroneous frame of the logarithmically coded digital signal and adding an attenuation value to a frame exponent of the erroneous frame.
