► Advanced Audio Amplifier ► DC BIAS First, what is the bias current of Q1 and Q2? The current through RE splits into Q1 and Q2, so we calculate Ic1 = Ic2 = 1/2 Ibias = 1/2 (VCC - VbeQ1) / RE = 1/2 (15 - 0.7) / 14.3k = 0.5 mA ...
For that reason, a large value gain trimmer was needed to cover all the bases. InFigure 1, you’ll notice that these trimmers (white) are installed and are single-turn. These made adjustment a little difficult and have since been changed to 25-turn pots as shown in the schematic diagram...
Fig. 9. This is the schematic for a Beat Frequency Oscillator metal-detector. Two transistors are used as the oscillators in this circuit. The circuit may be set up to operate on any frequency between 50,000 Hz to over 1 MHz by selecting the tank circuit components. Just about any good...

The capacitor C1 and the resistors R1 and R2 make up one T. C2, C3, R3, and R4 make up the other T. The schematic has it reversed. The component values must have the following relationships for this circuit to work properly:
It's designed to provide the power to an audio amplifier that intermittently draws the power required to produce 800 watts. To provide a continuous 800 watts of straight DC, the power supply would have to have approximately twice the components as this one. As a test, the prototype supply...
L7812CV Voltage Regulator: Schematic Diagram, Pinout, Circuit Diagram, and Datasheet Why Does Norway Take the Lead in the Adoption Rate of Electric Vehicles Related reading Marshall· November 25,2021What is an RC Snubber? The RC snubber is a kind of circuit that absorbs voltage spikes and prev...
Looking, now, at the schematic of the PS/2 mouse circuit board, the significance of the IR LEDs being connected to a pin on the microchip (instead of to the direct current) is obvious. The microchip controls the flashing of the IR LEDs through the I/O pin, and the microchip can corre...
typical schematic diagram of thin-film capacitors The film capacitor is a capacitor with a metal foil as an electrode, and a plastic film such as polyethylene, polypropylene, polystyrene, or polycarbonate, which is overlapped from both ends and wound into a cylindrical structure. And according to...
