    The procedure can be illustrated by a simple example presented by Zobel, [3]: 470 which is shown below. Here, the left hand lattice has a simple low-pass characteristic and the right hand lattice has the complementary characteristic. For this circuit R1*R2 = L1/C1 = L2/C2 = R0^2 with R1 < 2.R0 . C2 is given by = [()].

  3. Flip-flop (electronics) - Wikipedia

    en.wikipedia.org/wiki/Flip-flop_(electronics)

    The circuit shown below is a basic NAND latch. The inputs are also generally designated S and R for Set and Reset respectively. Because the NAND inputs must normally be logic 1 to avoid affecting the latching action, the inputs are considered to be inverted in this circuit (or active low).

  4. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    This circuit approximates the cut-in voltage present in real diodes. The combined I-V characteristic of this circuit is shown below: I-V characteristic of an ideal diode with a series voltage source. The Shockley diode model can be used to predict the approximate value of .

  5. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    Series RL, parallel C circuit with resistance in series with the inductor is the standard model for a self-resonant inductor. A series resistor with the inductor in a parallel LC circuit as shown in Figure 4 is a topology commonly encountered where there is a need to take into account the resistance of the coil winding and its self-capacitance.

  6. Current source - Wikipedia

    en.wikipedia.org/wiki/Current_source

    As a result, the output current is almost constant even if the load resistance and/or voltage vary. The operation of the circuit is considered in details below. A Zener diode, when reverse biased (as shown in the circuit) has a constant voltage drop across it irrespective of the current flowing through it.

  7. Tesla coil - Wikipedia

    en.wikipedia.org/wiki/Tesla_coil

    The common spark-excited Tesla coil circuit, shown below, consists of these components: [8] [12] A high-voltage supply transformer (T), to step the AC mains voltage up to a high enough voltage to jump the spark gap. Typical voltages are between 5 and 30 kilovolts (kV). [12]

  8. Relay logic - Wikipedia

    en.wikipedia.org/wiki/Relay_logic

    An NC contact would be shown as normally closed, and an NO contact would appear as a normally open device. All contacts associated with a device will change state when the device is energized. Figure 1 shows a typical relay logic diagram. In this circuit, a STOP/START station is used to control two pilot lights. When the START button is pressed ...

  9. Norton's theorem - Wikipedia

    en.wikipedia.org/wiki/Norton's_theorem

    Norton's theorem and its dual, Thévenin's theorem, are widely used for circuit analysis simplification and to study circuit's initial-condition and steady-state response. Norton's theorem was independently derived in 1926 by Siemens & Halske researcher Hans Ferdinand Mayer (1895–1980) and Bell Labs engineer Edward Lawry Norton (1898–1983).
