Tiivistelmä Tämä työ antaa katsauksen radioputkitekniikan nykyisiin oppimateriaaleihin, tarjoaa kevyen teoriakatsauksen putkivahvistintekniikkaan sekä analysoi valmiin SE/84 Braychera -putkivahvistimen kytkentää. Teoriaosuus on rajattu kattamaan vain esimerkkikytkennässä käytetyt tekniikat. Kytkennän analysointi painottuu etuasteen analysointiin, ja siitä analysoidaan jännitevahvistus, toimintapiste sekä ylä- ja alarajataajuudet. Työssä huomattiin, että putkitekniikan aikakaudella käytettyjä teorioita käytetään edelleen transistorivahvistimien kanssa. Operating principle of a valve amplifier Abstract This work provides an overview of current learning materials in radio tube technology, provides a brief theoretical overview of tube amplifier principles, and analyzes the circuit of SE/84 Braychera tube amplifier. The theoretical part of the work is limited to cover only the techniques used in the example circuit. The analysis of the circuit focuses on the preamplifier, and it covers the voltage gain, the operating point and the upper and lower limit frequencies. It was also noticed that many theorems that were used with tube amplifiers are still being used with transistor amplifiers. see all
