About :

COMPLETE ANALOG ELECTRONICS COURSE • The entire FREE Analog Electronics Course... In this class I show you a circuit where the JFET works as a variable resistor controlled by a voltage, which allows to vary the gain of the preamplifier by means of two push buttons to increase and decrease the amplitude of the signal that will be applied to an amplifier in the next stage and thus achieve a volume adjustment. The entire Analog Electronics course grouped into blocks and ordered the videos: Block 1: BASIC CONCEPTS • Block 1: CIRCUIT THEORY Block 2: CAPACITOR AND COIL in AC / DC • Block 2: CAPACITOR AND COIL in AC / DC Block 3: DIODES • Block 3: DIODES Block 4: TRANSISTORS • Block 4: TRANSISTORS Block 5: POWER AMPLIFIERS • How to avoid burning transistors. ... Block 6: OPERATIONAL AMPLIFIERS • Block 6: OPERATIONAL AMPLIFIERS Block 7: LINEAR VOLTAGE SOURCES • Block 7: LINEAR VOLTAGE SOURCES Block 8: SWITCHING VOLTAGE SOURCES SMPS • Block 9: SWITCHING VOLTAGE SOURCES SMPS Block 9: INVERTERS • Block 10: INVERTERS Channel ACadenas: / acadenas
