Abstract
Improvements in the tuning, conversion, amplification and detection circuits for television receivers, characterized in that the ultra-high frequency signals are made visible and audible by the use of a tuner and converter constituted essentially by two transistorized stages, of which the The first is high frequency with its transistor working on a ground basis, which reduces background noise to a minimum, the input being symmetric and the output asymmetric, while the collector circuit works at a quarter of the wavelength and the second stage is coupled by a band pass filter; the collector of the second transistor works at a higher frequency than the reception frequency and it is extracted, through a low-pass filter, the frequency resulting from the heterodination of the input signal, picked up by the antenna, and the signal produced by the local oscillator.
