such as inductors (L)‚ resistors (R)‚ and capacitors (C). They are then called LRC filters. In the lower frequency range (1 Hz to 1 MHz)‚ however‚ the inductor value becomes very large and the inductor itself gets quite bulky‚ making economical production difficult. In these cases‚ active filters become important. Active filters are circuits that use an operational amplifier (op amp) as the active device in combination with some resistors and capacitors to provide an LRC-like filter performance

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically

DeLorean DMC-12. The vehicle’s time displacement is powered by plutonium‚ which supplies 1.21 gigawatts of power to a device Doc calls the “flux capacitor” Doc explains that the car travels to a pre-set date upon reaching 88 miles per hour; as an example to Marty‚ Doc enters the date November 5‚ 1955 the date he came up with the concept of the flux capacitor. Before Doc can make his first trip‚ Libyan terrorists‚ from whom he stole the plutonium‚ arrive and shoot him. Marty attempts to escape using

picked up by the condenser microphone and converted into corresponding electrical signals. Resistor R5 and capacitor C3 decouple the power supply of the preamplifier stage. Resistor R1 biases the internal circuit of the low-voltage condenser microphone for proper working. The audio output from the preamplifier stage is fed to the input of the medium-power amplifier circuit via capacitor C2 and volume control VR1. The medium-power amplifier section is wired around popular audio amplifier IC TDA2822M
