Why buffer amplifiers are used if its gain is 1?
A buffer amplifier of unity gain is generally used when you need to islolate the source.Connecting a source to an amplifier, can have an affect on the original signal. A buffer amplifier stops the signal being affected by the subsequent amplifier sections. The input to the buffer is matched to the signal impedance.
How many ohms do you need for 4 overhead speakers?
You need some amplifiers.
For each of the following phrases indicate whether it occurs during transformation conjugation generalized transduction or specialized transduction by dragging it to the appropriate bin.?
I apologize, but I cannot drag items or interact with a visual interface. However, I can help you categorize the phrases related to transformation, conjugation, generalized transduction, and specialized transduction if you provide them. Please share the phrases you need help with!
Why do membranes need protein channels?
Membrane proteins are essential for facilitating the transport of substances across cell membranes, as they help maintain selective permeability. Many molecules, such as ions and large polar substances, cannot easily pass through the lipid bilayer due to their size or charge. Protein channels provide specific pathways that allow these molecules to move in and out of the cell, enabling critical processes like nutrient uptake, waste removal, and signal transduction. This selective transport is vital for maintaining cellular homeostasis and overall function.
Why would ADP act as an inhibitor in catabolic pathways?
ADP can act as an inhibitor in catabolic pathways because an increase in ADP levels can signal that the cell has a sufficient amount of ATP and does not need to further break down nutrients for energy production. This feedback mechanism helps regulate metabolic processes and prevent unnecessary energy expenditure.
What are the most used instrument amplifiers?
The most used instrument amplifiers are also some of the most popular amplifiers namely Marshall, Crate and Fox amplifiers. The impedance of these amplifiers does not need to match making it perfect for instrument use.
What all do you need to put more bass into a car?
Amplifiers and better speakers. But amplifiers are a must.

What the need for amplifiers used in biomedical applications?
Amplifier is a electronic device. It is a combination of transistors & FET. To give an input signal to an amplifier, it does not change the value of frequency & waveshape .It increase only the value of amplitude.
Do guitars need capacators?
No, a capacator is used in amplifiers.

How does sound travel from an instrument to your ears?
When we speak in a microphone it converts into the electrical signal with the help of transducer. Transducer is a device which converts one form to another which we can further amplify for proper transmission of signal to long distances with he help of amplifiers. After that we need a proper way for transmission. When we receive that signal at the output we again use a transducer for again conversion of signal from one to another i.e., from electrical to sound and after that we can listen that sound.

Do I need to worry about car amplifiers blowing out my speakers?
Yes -- speakers and amplifiers should be properly matched by power rating and impedance to avoid damage to either component.
In RC coupled amplifiers ac input is fed through a capacitor with capacitors positive terminal attached to base Why not plus ve terminal of capacitor attached to ac power supply?
In RC coupled amplifiers (more correctly, AC coupled amplifiers), you couple the input signal to the base of the transistor with a capacitor so as to not disturb the DC bias voltage for the transistor. Often, in a class A amplifier, there is a DC offset or bias on the base, while the input signal is centered around zero. The capacitor allows this voltage differential, while acting as low pass filter, allowing the input signal to drive the base.This was more important in vacuum tube circuits, where the grid bias was often quite a large negative voltage.You need to consider the frequency rolloff that will be tolerated in the low pass filter.Operational amplifiers solve this problem by allowing the reference and feedback voltages to be zero, allowing a DC coupled design.
