So, going back to our truth table, let’s look at the logic required to get ‘Sum’ based on the inputs A and B. Here we want the logic to output one only when one input is one and not the other, this is known as an exclusive OR gate. We can do this by simply using two AND gates with NOT gates on opposing inputs. If either gate outputs a 1 the result is 1 via the final OR gate.
Magnetic stripe reader circuitbyLuis Padilla Visdomine.Using the softwareThe magnetic strip reader should be connected to the joystick port (output of the reader to pin 2 and ground to pin 4) or to the parallel port (output of the reader to pin 15 and ground to pin 18) of a PC if you are going to use the software provided in these pages.
舞蹈发光二极管电路。Whishing to use a lower number of LEDs or LED strips, pin #15 of IC2 must be disconnected from ground and connected to the first unused output pin.Whishing to use a wall-plug transformer-supply instead of a 9V battery, you can supply the circuit at 12V, allowing the use of up to 6 LEDs per strip, or at 15V, allowing the use of up to 7 LEDs per strip.
Push-Pull Output StagePush-Pull Output Stage.One advantage is that there''s no power dissipated in the output transistors when there is no signal present. (The Class A stage requires significant bias - and dissapates lots of heat - even with no input signal.) One disadvantage of the push-pull is the distortion of the signal near 0V. Distortion can be a dirty word, especially to audiophiles.
Pin 8 (V +): The V+ pin (also referred to as Vcc) is the positive supply voltage terminal of the 555 timer IC. Supply-voltage operating range for the 555 is +4.5 volts (minimum) to +16 volts (maximum), and it is specified for operation between +5 volts and + 15 volts.That is because the output is only triggered by the input pulse, the output actually depends on the capacitor charge.

电容倍增器(capacitance multiplier)电源滤波器的电路图Introduction.So the regulator will have a minimum input voltage of 25.4 Volts, and a maximum of 35V, so power dissipation will be:6.75 Watts average at minimum input voltage and 1.25A average current18.75 Watts average at maximum input voltage (also at 1.25A)Somewhere in between for nominal mains supply voltages and output current variations.
原文:  This project uses an LM3915 bar-graph IC driving two sets of ten LEDs for a 30dB range. The circuit is unique because it has an additional range of 20dB provided by an automatic gain control to allow it to be very sensitive to low sound levels but it increases its range 20dB for loud sounds.2) You could use an LM358 dual opamp (I tried it) but its output drops above 4Khz.

红外门电路2例 (Infrared gate 2)The receiver diodes must be properly shielded from the transmitter LED(s) otherwise the infra light will surely drive the receiver with a large enough signal.If everything is ok, holding a mirror in front of the LED panel will reflect enough signal to overdrive the amplifier and you can check the output on the OPA 1, 7 pins with an oscilloscope.

To achieve quantum supremacy, a quantum computer would have to perform any calculation that, for all practical purposes, a classical computer can’t.In place of a die, this candidate problem for quantum supremacy asks a computer to correctly sample from the possible outputs of a random quantum circuit, which is like a series of actions that can be performed on a set of quantum bits, or qubits.

Amplifier Classes and the Classification of AmplifiersAmplifier Classes Explained.Class A Amplifiers are the most common type of amplifier class due mainly to their simple design.We have seen here a number of classification of amplifiers ranging from linear Power Amplifiers to non-linear switching amplifiers, and have seen how an amplifier class differs along the amplifiers load line.

The Neural Network Zoo.Once trained for one or more patterns, the network will always converge to one of the learned patterns because the network is only stable in those states.Deep residual networks (DRN) are very deep FFNNs with extra connections passing input from one layer to a later layer (often 2 to 5 layers) as well as the next layer.

Perfect for driving LEDs!
Power Tip 38: Simple latch circuit protects power supplies.Have you ever needed a simple, inexpensive latch circuit?If the latch is connected across a capacitor that is fed with a small current, the latch discharges the capacitor.If R14 and R16 are small in value, the latch turns off and the bias capacitor recharges, and the power supply tries to provide output power again.
Introduction: World of microcontrollersuction: World of microcontrollers.A logic gate “AND” has two or more inputs and one output. Let us presume that the gateused in this case has only two inputs. A logic one (1) will appear on its output onlyin case both inputs (A AND B) are driven to logic one (1).Microcontrollers using this architecture have only one memory block and one 8-bit data bus.
