Abstract
Sposób sterowania głośnością, dotyczy odbiornika, w którym tor foniczny zawiera, od strony wejścia antenowego, wzmacniacz wielkiej częstotliwości WWC połączony na wyjściu z wejściem mieszacza MIE, a wyjście mieszacza MIE jest połączone z wejściem wzmacniacza pośredniej częstotliwości WPC, połączonego poprzez demodulator DEM ze wzmacniaczem małej częstotliwości WMC z wyjściem głośnikowym lub słuchawkowym. W odbiorniku wybiera się rodzaj wzmacnianego dźwięku, w postaci mowy lub muzyki, po czym w tym odbiorniku prowadzi się na bieżąco detekcję rodzaju nadawanego dźwięku, a następnie wzmacnia się ten wybrany rodzaj dźwięku lub osłabia się pozostałe dźwięki. Układ sterowania głośnością zawiera układ detekcji (UDR) rodzaju odbieranego dźwięku, w postaci mowy lub muzyki, połączony na wejściu z wyjściem regulacyjnym jednego z podzespołów fonicznych toru fonicznego odbiornika, zaś na wyjściu z układem wyboru (UWR) rodzaju i wzmocnienia dźwięku, którego wyjście jest połączone z wejściem regulacyjnym innego ze wspomnianych podzespołów fonicznych.The loudness control method relates to a receiver in which the audio path comprises, from the antenna input side, a high frequency amplifier WWC connected at the output to the input of the MIE mixer, and the output of the MIE mixer is connected to the input of the intermediate frequency amplifier WPC connected via a DEM demodulator with a low power amplifier. WMC frequencies with speaker or headphone output. The type of amplified sound, in the form of speech or music, is selected in the receiver, and then in this receiver the type of the transmitted sound is detected on an ongoing basis, and then the selected type of sound is amplified or other sounds are weakened. The volume control system includes a system of detection (UDR) of the type of received sound, in the form of speech or music, connected at the input to the control output of one of the audio components of the receiver's audio path, and at the output to the selection circuit (UWR) of the type and amplification of the sound, the output of which is connected to a control input of another of said audio components.
