What is the definition of audio-frequency transformer?
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
How can you connect your 2 home receivers and 2.1 hi-fi amplifier and subwoofer together?
To connect two home receivers with a 2.1 hi-fi amplifier and subwoofer, first, designate one receiver as the primary source. Connect the audio output of the primary receiver to the input of the 2.1 amplifier using RCA cables. Then, connect the subwoofer to the amplifier's dedicated sub output. For the second receiver, use its audio output to connect to the primary receiver's audio input if needed, or use a switch to alternate between the two receivers.
What causes squeal or noise in a sound system?
A loud "squeal" or "screech" - also known as "feedback noise" - is usually only generated if there is an audio input device for an amplifier, for example a microphone, that is being used too close to an audio output device for the same amplifier, for example a speaker.
Viva questions for RC phase shift oscillator?
A phase-shift oscillator is a simple electronic oscillator circuit. It consists of an inverting amplifier element such as a transistor or op amp, with its output fed back into its input through an filterconsisting of a network of resistors and capacitors. The feddback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency, to give positive feedback.[1] Phase shift oscillators are mostly used at lower frequencies, often in the audio frequency range as audio oscillators.
What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
How sound amplifier circuit works?
A sound (audio) amplifier works by making a larger copy, or series of copies, of a weak signal.
Which is the best audio amplifier IC for amplify audio signal?
the radio has an input amplifier bt u can also make a simple horm circuit...... or but a jec 600 n dat will du
Can someone show you electrical circuit diagram for a voki toki?
A walkie talkie circuit diagram typically consists of a microphone, speaker, antenna, oscillator, amplifier, and power supply components. These components work together to transmit and receive audio signals wirelessly. The circuit diagram may vary depending on the specific model and features of the walkie talkie. It's best to refer to the manufacturer's documentation for accurate schematics.
What can replace an audio amplifier LM380?
The LM380 can be replaced by other audio amplifiers with similar specifications, such as the LM386 for low-power applications or the TDA2030 for higher power requirements. Additionally, the LM487 and TPA3110 are modern alternatives that provide improved efficiency and performance. It's important to ensure that the replacement matches the voltage, current ratings, and required output power for your specific application.
Which amplifier is provided with a bootstrap?
audio amplifier
Will connecting speakers in series cause volume loss as the circuit progresses?
Yes. And it will also present the wrong load impedance (mismatch) at the output of the audio amplifier, with the possibility of damage to the amplifier.
Were do you buy a voltage amplifier?
In audio look at an amplifier. It will be always a voltage amplifier.
Are there any logic chips that could be used to process audio?
I've seen a Logic chip, 2 input quad NAND gate IC, that was set up as a Audio amplifier circuit.
What would be the purpose of a headphone amplifier?
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
Which circuit component usually ask as a switch or amplifier?
The transistor is the circuit component that typically acts as a switch or amplifier. In switching applications, it can control the flow of current through a circuit, while in amplification applications, it increases the strength of weak electrical signals. Transistors are fundamental in modern electronics, enabling various functions in devices ranging from computers to audio equipment.
What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
