Analog television signal processing method and device

The invention discloses an analog television signal processing method and device. The method comprises the following steps: converting the frequency of a received analog television signal into an intermediate frequency to obtain an intermediate frequency analog signal; judging whether the intermediate frequency analog signal has an adjacent channel meeting a preset condition or not; if so, pre-filtering the intermediate frequency analog signal to obtain a pre-filtered signal; performing IQ imbalance estimation on the pre-filtered signal to obtain an estimation result; performing digital phase-locked loop processing on the estimation result to obtain a signal after digital phase locking; performing IQ compensation on the signal after digital phase locking to obtain a compensation signal. According to the method disclosed in the invention, the effect of improving the signal quality of the analog television is achieved. 本发明公开了一种模拟电视信号处理方法和装置。该方法包括：将接收到的模拟电视信号的频率变换到中频，得到中频模拟信号；判断中频模拟信号是否存在满足预设条件的邻频；如果存在，则对中频模拟信号进
