摘要： This disclosure presents an apparatus and method for automatic gain control correction for a television signal in which the Radio Frequency (RF) and Intermediate Frequency (IF) power signal levels are collected for a band of channels, identifying a channel having a strong RF power signal level and an IF gain signal level that is lower than a nominal IF gain signal level, comparing the identified channel RF gain signal level with the RF gain signal level of adjacent channels to identify the relative power signal levels of the channel and associated adjacent channels, and applying correction to the channel wherein there is an imbalance in the RF and IF power signal levels of the identified channel. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A method of spot welding aluminum alloy workpieces having electrical conductivity of 18.about.57% IACS and Vickers hardness of 26.about.200 is disclosed. The aluminum alloy workpieces are spot welded by a pair of welding electrodes having an electrical conductivity of not less than 92% IACS and a Vickers hardness of 50.about.130. The differences of the electrical conductivity and Vickers hardness between the welding electrodes and the aluminum alloy workpieces are in a range of 41.about.87% IACS and not larger than 99, respectively.

摘要： A band-pass filter separates an audio intermediate frequency signal from an input intermediate frequency signal, and an A/D converter circuit converts the audio intermediate frequency signal into a digital signal. A DSP performs audio detection on the digital signal and forms an AGC signal based on the signal. A variable gain amplifier performs AGC on the audio intermediate frequency signal in response to the AGC signal. A bandpass filter separates and takes out a video intermediate frequency signal from the signal, and an A/D converter circuit converts the video intermediate frequency signal into a digital signal. A DSP performs video detection on the signal. An AGC signal is formed based on the signals and AGC is performed on the video intermediate frequency signals by using the AGC signal.
