A circuit in which output feeding back to input to increase or decrease the gain is called feedback circuit. Basically part of output feeding to input in such way that it increase the value of input is positive feedback and it also increase gain of circuit and similarly to it when part of output feeding to input in such way that it decrease the value of input is called negative feedback it also decrease the gain of circuit.
What else can I help you with?

What type of feedback is used in the phase shift oscillator circuit?
Positive feedback
What is the Purpose of feedback circuit?
To improve anaerobic endurance
Why emitter bias circuit is called self bias circuit?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
Why negative feedback amplifier is preferred to positive feedback amplifier?
The negative feedback tends to stabilize the circuit; positive feedback would make it more unstable. For example, the "beta" of a transistor OF THE SAME SERIES - this is basically the amplification factor - may vary between 100 and 1000. With negative feedback, the circuit is hardly affected by these changes in beta - at the cost of a reduced amplification.
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 is role of LC circuit in the hartley oscillator?
Self-tuning feedback
How do you introduce feedback circuit in dc motor speed control?
By using your brain
What are the condition for oscillation?
There are three conditions. These include positive feedback, the phase near the circuit needs to be either 36 or zero degrees, and the loop gain should be equal or greater than 1.
What type of feedback used in the oscillator circuit?
There are many different types of oscillator circuits, the majority of which use positive feedback.
What negative feedback in a circuit?
A part of output which is provided again ti theinput but with some phase difference is called negative feedback. i hope u get it..
What is floating load?
A load not connected to ground but connected in a feedback circuit is floating load
