A dual-mode transmitter (100) adjusts a signal's deviation level when switched between a wideband mode and a narrowband mode of operation. The transmitter (100) automatically attenuates the deviation of the signal based on a ratio of the maximum deviation level for the wideband mode to the maximum deviation for the narrowband mode utilizing wideband/narrowband maximum deviation adjust circuitry (115). Because the attenuation based on the ratio of the maximum deviation levels is too large for a narrowband mode signal having average deviation, the signal is amplified based on a ratio of the average deviation level for the wideband mode to the average deviation for the narrowband mode utilizing wideband/narrowband average deviation adjust circuitry (103). Attenuation and amplification of the signal's deviation occur when the dual-mode transmitter (100) is operating in the narrowband mode.

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.
