摘要： A tuning apparatus (100) compensates for temperature-related frequency variations of a filter (130). According to an exemplary embodiment, the tuning apparatus (100) includes an RF signal source, a tuner (110), and the filter (130). The tuner (110) includes a local oscillator (120) and is coupled between the RF signal source and the filter (130) and provides an IF signal for the filter (130). The tuner (110) also includes a frequency adjustment mechanism (126) for adjusting the frequency of the local oscillator (120) in response to a temperature characteristic of the filter (130).

摘要： A television signal processing apparatus is capable of receiving emergency alert signals and providing alert outputs to notify individuals of emergency events. According to one exemplary embodiment, the television signal processing apparatus includes a tuner (22) operative to tune a frequency including emergency alert signals indicating an emergency event. A processor (27) is operative to cause the television signal processing apparatus to be switched from an off/standby mode to an on mode responsive to the emergency alert signals.
