14 Watt car audio amplifier circuit Schematic Diagram

The introduction for a unidirectional thyristor trigger circuit is also applicable to the TRIAC. Various configurations are presented in Figure 16-28. Figures 16-28 (a) and (b) illustrate a direct trigger circuit; Figure 16-28 (c) depicts a dual diode trigger...

The proposed scheme is straightforward, requiring only a few external electronic components, making it suitable for car audio construction. The output power ranges from 2 to 4 Ohms, providing 2 x 30 W (with a maximum of 2 x...

Figure 2-33 (a) illustrates the schematic diagram of a robot approaching an object. When no objects are detected in front of the robot, it moves forward in a straight line. If an object is detected on the left or...

This circuit is designed to work at UHF frequencies in the range 450-800MHz. It has a gain of around 10dB and is suitable for boosting weak TV signals. The circuit is shown below. The described circuit operates within the Ultra...

A 100 W output at 50 MHz is available from this circuit. U1 and Q2 form a T-R relay driver, switching the amplifier on when RF input at J1 is sensed. During receive periods, J1 and J2 are directly...

The circuit can function as a sensitive current detector or a voltage detector with high input impedance. Resistor Rl is configured so that the voltage at point (A) is V2 to a few volts below the threshold that activates...
