RANGKAIAN PENGUAT OP-AMP (LM 741)

An Rangkaian OP-AMP (operational amplifier), which is often called an op-amp, is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single output.

Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices. Many standard IC op-amps cost only a few cents in moderate production volume; however some integrated or hybrid operational amplifiers with special performance specifications may cost over $100 US in small quantities.

Modern designs are electronically more rugged than earlier implementations and some can sustain direct short circuits on their outputs without damage.

Inverting amplifier
Op-Amp amplifier turn will strengthen the input voltage and reverse the results of such reinforcement, so the output of this circuit will always have a berlawananan polarity input signal.

Amplifier is not turned
In this configuration the feedback is used to regulate the grant of permanent strengthening of the input reversed, but the Vin on the input provided was reversed so that the output voltage will always sefasa with input voltage.

Summing amplifier voltage
By using the basic inverting amplifier circuit and adding a resistor on the other input, we can make a summing amplifier reverse. Output voltage will be reversed and it is equal to the algebraic sum of each input voltage multiplied by the result for the input resistor with a resistor corresponding feedback

RANGKAIAN TONE CONTROL

Rangkaian tone control circuit ia an electronic circuit used to modify an audio signal before it is fed to speakers, headphones or recording devices by way of an amplifier.

Gambar Rangkaian Tone Control

Tone control circuits exist for many reasons. One is to allow listeners of recorded or broadcast music to adjust the sound to their liking. The adjustment may be necessary as a result of recording deficiencies, hearing deficiencies, listening room acoustics or playback equipment deficiencies. For example, some people prefer an attenuation (reduction) of the "strength" (amplitude) of the higher pitched tones, while many older people, who may have a hearing problem, prefer an emphasis of them. Another is to make adjustments to a musical signal prior to recording, e.g., when the acoustics of the recording site absorb some frequencies more than others.

Historically, all of this has been done via analog electronics and most tone control circuits produced today still use the analog process. However, digital electronics approaches to this function are increasingly being implemented through the use of digital signal processing.
In this section discussed the tone control using TDA 1524 IC a type that includes all volume settings bass and treble balance in a single IC TDA 1524 a. arrangements made with the potentiometer, which in a matter of the circuit, the change potensio working voltage at the central ic.
