1. Negative feedback can increase linearity at the expense of losing gain.
2. & 3. Positive feedback can result in large increases in gain until the increases becomes so large that oscillation occurs.
4. Positive or negative feedback at one frequency can result in enhanced or decreased response to that frequency.

What is buffer amplifier and its applications?
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
Does paper jams guiter need a amp?
Yes, a paper jams guitar typically requires an amplifier to produce sound. This type of guitar, which is often made from unconventional materials like paper, is designed to function as an electric instrument. Without an amp, the sound produced would be minimal and not suitable for performance. Connecting it to an amp allows for amplification and effects that enhance its unique sound.
What are the effects of metal impurities in iron?
Metal impurities can have many different effects on iron. Some of these effects may include, but are not limited to differences in strength, chemical inertness, and flexibility.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
How the noise is overcome with the help of positive feedback amplifier?
A: With positive feedback the amplifier is saturated one way or the other in a quiescent state no signal or noise input can effects its output
Explain how negative feedback in an amplifier helps in reducing the distortion?
A: An amplifier operates withing its open loop response a negative feedback insure that the amplifier remains in its linear region. therefore reducing effects of saturation, storage time to name a few.
How do you minimize feedback on tons of effects plugged into an amp?
Get a noise gate. or turn down the volume level on your distortion. or turn down the regeneration on your delay or stand farther away from your amp or turn your amp down. feedback is because your guitar pickup is looping the sound coming out of the amplifier back through all your effects again then through the amplifier then back through your pickups and so on
What does an electric guitar do?
its a solid body guitar that allows you to amplify and apply different effects to the sound by means of an amplifier.
What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
What type of feedback exaggerates the effects of variations from normal?
posistive feedback
How has the guitar pedals assisted with technology of the guitar and sound quality?
Guitar effect pedals were invented in the late 60's and more development into effects came in the 70's. The purpose of the effect pedal, namely the ever popular distortion, overdrive, feedback and delay pedals, was to eliminate the need to crack amplifier tubes and overdriving the feedback by proximity to the amplifier. Later, flanger, phaser and Hendrix's heavy use of the Wah-Wah effect became increasingly popular through sound shaping and dynamics. Most pedals are used do avoid amplifier and instrument abuse and damage. The sound dynamics from a pedal is designed to give the guitar the best effect based on varying conditions; loudness, regular amplifier distortion and feedback, the general acoustics of the venue, the amplifier cabinet type... the possibilities are limitless.
What are the key features to consider when choosing a guitar amplifier head for optimal performance?
When choosing a guitar amplifier head for optimal performance, consider the wattage for volume, the number of channels for versatility, the type of tubes or transistors for tone, the effects loop for adding effects, and the speaker output options for connecting to different cabinets.
How shall you connect pedal effects to a fender amplifier with send in send out jacks?
The send out of the amp to the in of the effects, the out of the effects to the send in of the amp.

What are the key features and benefits of a 2 channel guitar amplifier?
A 2 channel guitar amplifier allows you to switch between two different sound settings, giving you versatility in your tone. This can be useful for switching between clean and distorted sounds, or for using different effects. The benefits include more flexibility in your playing style, the ability to easily switch between tones during a performance, and the opportunity to experiment with different sounds and effects.
Where are Effects greater than their cause?
In systems with positive feedback (or multiplier effects).
