TEA6101/T Intended for multi-antenna FM car radio reception (antenna diversity system), the TEA6101/T selects the most favourable signal from one of up to four antennae. Founded upon audible signal disturbance the criteria are derived from two signals: high frequency components (e.g. spikes due to noise and multipath reception) and variations in signal lev.
• Ability to switch between up to four antennae
• Switching signal derived from two signals: the audio and the level signals
• Floating switching threshold adjusts switching rate to prevailing circumstances:
– increasing threshold due to excessive noise
– increasing threshold due to numerous level variations
• Memory for the most favourable antenna signal to overcome unnecessary switching
• Signal-dependent `soft` muting circuit
• Mode selection to the first antenna receiving an AM signal whilst the diversity system is reset. APPLICATIONS
• Car radio receivers
• Mobile radio communications equ.
