Hum in amplifiers is typically caused by unwanted electromagnetic interference, often from nearby electrical devices or power sources. This interference can induce a low-frequency noise, often at 60 Hz (or 50 Hz in some regions), into the audio signal. Ground loops, poor shielding, and inadequate filtering can also contribute to this hum. Proper grounding, shielding techniques, and using high-quality components can help minimize this issue.

Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
What is the effect of emitter resistance in common emitter amplifier?
The gain of a common-emitter amplifier is collector resistor divided by emitter resistor, or hFe, whichever is less. Since hFe depends on temperature, designing the amplifier to be dependent on resistance ratio makes it more stable. As such, the emitter resistance serves to stabilize the amplifier.
What is a direct coupled amplifier?
Quite simply, it's an amplifier wherein the stages as set up so that the output of one stage is coupled directly into the input of the next stage without any wave shaping or tuninig components between them. This makes for fairly flat frequency response. A link is provided to the Wikipedia article on direct coupling.
What is the difference between normal amplifier and magnetic amplifier?
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
What is the difference between an amplifier and a speaker?
The subwoofer is the actual speaker making the loud bass. The amplifier is what powers the subwoofer and makes it work how it does. It only uses the low frequencies from the audio source and amplifies it.
Does hum have a short vowel sound?
No, "hum" does not have a short vowel sound. The "u" in "hum" makes a long vowel sound as in "soon" or "moon."
What do you call the sound an impala makes?
A very quiet hum.
What is the amplefair?
Do you mean amplifier? An amplifier, when attached to something (such as an electric instrument), makes the object's sound louder.
What are the symptoms of a bad phase inverter tube in a tube amplifier?
Symptoms of a bad phase inverter tube in a tube amplifier may include distorted or weak sound output, loss of volume, excessive noise or hum, and unbalanced tone.
Why you need operational transconductance amplifier?
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
What is the sound an alpaca makes called?
If you mean what sound does an alpaca make when they call, they hum.
What is different amplifier and rectifier?
An amplifier makes a (generally larger) copy of a signal or voltage. A rectifier allows current to pass in only one direction.
Can you switch a 1800 microfarad with a 2200 microfarad capacitor?
A: I hope you mean replace. The answer is yes provided that the voltage rating is the same or more then the original.
What does amplifier do to a sound?
It makes the sound more grand by electricity and the flick of a switch.
Vehicle makes noise only in morning?
What kind of noise? Hum/click/rattle/knock/squeal?
How do you spell the sound a yawn makes?
The typical written expression for a yawn sound is "ho hum."
What is effect of load on voltage gain of common emitter amplifier?
it makes sound :) trollolololol
