Can a transistor be used to switch audio?
If you really want to switch audio with little more than a simple transistor, consider a circuit like this: Basically what you do is short the input to ground by enabling the transistor. Disadvantage is that the output level will be at least 6dB lower than the input level.
Is it OK to switch line level audio signals?
The super quick answer is: None of the parts that you have selected are appropriate for switching line-level (headphone level) audio signals. Off Topic Rant: It is often ill-advised to restrict the parts or techniques used in the answers. I covered this briefly in an answer on meta.EE.SE: Does EE.SE have a problem with the treatment of newbies?
How is an amplifier used in an audio system?
Audio Amplifier is a device which strengthen the weak signal. Usually in audio systems we use amplifiers to drive the speakers of high power rating . Now , in this Instructables you are going to see how to make an audio amplifier using single transistor to drive the speaker of 10W .
Who is the inventor of the audio amplifier?
I am Junez Riyaz, currently doing Bachelor of Technology in the field of Electronics and Communication Engineering. I am much interested in inventing something new yet from my childhood. In my leisure time… More About JunezRiyaz » Audio Amplifier is a device which strengthen the weak signal.
How are input and output transistors used in a switch?
The first or “input” transistor receives the input signal to its Base. This transistor amplifies it in the usual way and uses it to drive the second larger “output” transistors. The second transistor amplifies the signal again resulting in a very high current gain.
How does a Darlington transistor work as a switch?
Darlington Transistors simply contain two individual bipolar NPN or PNP type transistors connected together so that the current gain of the first transistor is multiplied with that of the current gain of the second transistor to produce a device which acts like a single transistor with a very high current gain for a much smaller Base current.
When does a transistor switch on or off?
After a certain period of time, which can be determined by the choice of resistor and capacitor, the transistor is either switched on or off.
How is a load connected to a transistor?
When a change in signal takes place by reaching a pressure value, the supply voltage (U+) is “switched through”, allowing current to flow from U+ through the transistor and through the load to GND. The load is connected to the switching output with U+ as the reference point.
