Dye lasers are unique in that they are a class of lasers whose lasing medium is a liquid. Depending on the particular dye used, output can be at a wide range of wavelengths spanning the visible spectrum and beyond. Commercial dye lasers are often pumped by....

If a linear feedback amplifier contains reactive elements, and at some frequency the loop gain Ab = -1, sinusoidal oscillations will be obtained. The sine wave oscillators investigated in this experiment consist essentially of two separate but connected....

The following circuit shows about Bass And Treble Controller Circuit. This circuit built based on the classic Baxandall tone control circuitry ....

The circuit was based on a single operational amplifier integrated circuit that is made to produce a modular preamplifier which functions in the Class A o....

The distortion produced by a typical solid-state Class-B power amplifier is shown to consist of eight mechanisms, all of which may co- exist and whose distortion products overlap to give a complex result. Methods for isolating each mechanism for study, and....

The classic Rangemaster is thought to have been the source of some of the best tones in rock guitar, from Clapton`s Beano sound to some of Brian May`s singing sustain tones. While the effect is a simple one-transistor booster, locating a good quality....

This electronic project stereo amp is based on the STK415-090-E class H audio power amplifier hybrid IC that features a built-in power supply switching circuit. This STK415-090-E class H audio power amplifier provides high efficiency audio power....

Not thrilled with how a computer soundcard drove my 32ohm headphones so I decided to build myself class-A mosfet headphone amplifier. As with most of my projects, the goal was to keep it simple, keep cost down and try use some salvaged parts. This is a....

The HARTLEY OSCILLATOR is an improvement over the Armstrong oscillator. Although its frequency stability is not the best possible of all the oscillators, the Hartley oscillator can generate a wide range of frequencies and is very easy to tune. The Hartley....

Zilog`s Z8 Encore XP F1680 Series incorporates a best-in-class feature set that is optimized for stepper motor microstepping controls. The features of Z8 Encore! XP F1680 include: A fast 11 MHz internal Oscillator Two Analog Comparators 10-bit....

A class-A audio amplifier is pretty wasteful of power but when plenty of power is available the simplicity is attractive. Here is a simple darlington transistor example intended for use with a 5 volt power supply. This circuit and the following aren`t for....

Since then NL has evolved into the Microsoft Windows ®-based NL4, which has been used extensively by world-class engineers in different fields of electronics for almost 10 years. NL5 is the first version to be publicly available. Unlike conventional....

This solid-state push-pull single-ended Class A circuit is capable of providing a sound comparable to those valve amplifiers, delivering more output power (6. 9W measured across a 8 Ohm loudspeaker cabinet load), less THD, higher input sensitivity and better....

It`s based on a Philips class-H audio amplifier IC and can deliver 36W RMS OR 70W music power, all from a 13.8V supply. Our new Mighty Midget Amplifier can really pack a punch - around 36W RMS continuous into a 4-ohm load when using a 13.8V supply. However,....

This audio amplifier circuit is useful in classrooms to reduce the strain of lecturing, if the surrounding environment is noisy. It uses the power amplifier IC LM380 that gives 2 watts output which is sufficient in a confined area. The amplifier is portable....

Too much of a good thing can confuse you. I started out looking to build a simple 15W triode / 30W Class AB1 pentode PP amplifer. Class AB1 = because....

The circuit was constructed around the functionality of a Class A amplifier to create a headphone circuit. BC308 an epitaxial planar PNP transistor used....

This weekG•s plan is to build a device that warns of the potential of a knockdown the process by which an over-canvassed ship is lain over on her beam-ends. The potential for sinking at this point is high, so it is an event to be avoided. As the reading of....

MIDI, the Musical Instrument Digital Interface, is a useful protocol for controlling synthesizers, sequencers, and other musical devices. MIDI devices are generally grouped in to two broad classes: controllers (i. e. devices that generate MIDI signals based....

A step-up converter followed by an LDO regulator offers better battery life than a classic SEPIC design when operating from one lithium-ion cell....

This class A preamplifier has been designed in a symmetrical structure. In the input differential stages we`ve used the dual transistors T1 and T2. Polarisation correction is essential because of the amplification differences and is assured with T12. P2....

All of the parts in this list are generally available through Radioshack for less than $20. I highly recommend using breadboard! You`re bound to make mistakes your first time and soldering it will only make your fail worse (double fail ). I`ve compiled this....

These are two - easy to build - relay-based alarms. You can use them to protect your motorcycle - but they have many more applications. If you use relays with 6-volt coils - they`ll protect your "Classic Bike". Both alarms are very small. The completed....

When feed power supply reach the circuit and feed input signal come in. The sound signal change C1 and R1 for signal coupling and eradicate noise oscillator go out. From that time go to reach input pin 3 non inverting of IC1. Which be op-amp IC boost up....

This is a schematic diagram of stereo audio amplifier for your car. The circuit is powered by a single IC TDA1553 with some external components, this IC will handle your stereo car audio system. The TDA1553CQ is a monolithic integrated class-B output....

V1 and V2 are set to 5V in the simulation, but could also be 10V to eliminate the need for a second supply ” or, if you can find logic level FETs at that high a voltage, then you can reduce the 10 volt supply to 5 volts. Assuming that the switching frequency....
