What else can I help you with?
Can you connect a two-way radio external speaker output to the stereo speakers so that it will override the stereo signal when you get a call?
Yes, absolutely you can. The difficulty is that the controller needed to do the job is not something that can be bought off the shelf. Here is one idea to make the system work: First, take the output from the communications radio and establish the signal characteristics. You may need an attenuator to reduce the voltage of the signal. Once the signal is at the right level, it will need to be connected to an input on the stereo. Additionally, a sensor that will detect an audio signal on the comms radio output or a sensor that detects a valid radio signal on the comms radio is needed. Use the sensor output to trigger a switch from the current input to the comms radio input on the stereo. As an alternative, the same sensor output can be used to switch the speaker signal from the stereo to the comms radio. You will need a separate amplifier to do this as well as a suitable signal switcher to select either of the two speaker signals. The solution is not particularly difficult for an engineer to produce but it is not a straightforward job either.
Is amplification the act of tuning a radio to select a particular broadcast station?
Amplification is the process of making a signal louder. It is not the same as tuning a radio receiver. An amplifier is a device that takes a signal and makes it bigger as it reaches the amplifier's output. It can make the signal bigger by increasing the voltage, increasing the current or increasing both current and voltage, known as power amplifiers. Audio amplifiers that drive a loudspeaker are power amplifiers as they increase the power of the signal to drive the speaker itself. Tuning a radio adjusts the frequency that the radio aerial is sensitive to and allows only one frequency to be captured by the circuit attached to the aerial. By doing this, the radio can pick up a single broadcast and reject others. Before we can hear the received radio signal, it will be passed through a power amplifier and then to the speaker.
White bias-line equation?
An amplifier is what increases a rock band's speaker sound output into a ear splitting experience and small radio signals in a radio until it makes it out to the speaker. A transformer converts AC electricity up or down to a desired level for a required project. Example: A battery charger plugged into a wall socket will transformed to about 18 votls to do the charging. Speaking in technical terms, an amplifier is a device which increases the power of a signal by either increasing the voltage or current or both. Whereas, a Transformer is a device which simply transfers power, i.e., the energy on both input and output is the same. In the case of an amplifier, the output power is higher than the input power. This is because of the power input we give to an amplifier.
Are amplifiers input or output devices?
An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
Why op amp are called linear devices?
the output has the same shape of the input signal
Who travel faster a radio signal or light in space?
They are the same physical phenomenon, with the same identical speed.
Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
Why terminals of opamp are called as inverting and noninverting?
In an op-amp, an input on the inverting terminal drives the output in the opposite direction, while an input on the non inverting terminal drives the output in the same direction. In a normal closed loop negative feedback configuration, there is feedback from output to inverting input, so that the output becomes a known function of input. So long as you stay within limits, the output will go to whatever value is required to make the inputs be the same.
What is an integrated module?
A device that will allow you to send a FM signal. Usually used for mp3 or satelite radio players. You can set the modulator to a channel then your radio to the same channel and pick up the signal.

Why positive feedback unstable?
A: To feedback more of the same signal from the output to increase the input to farther increase the output and farther increase the input will ultimately saturate the system
What does amplifier do to a small input signal?
makes it bigger! (or sometimes smaller, or sometimes the same, but with lower output impedance)
