It never referred as ratio but Rather a gain A in the form of output divided by the input and implies voltage A=gain. basically is input resistance divided by the feedback resistance

Am amplifier that inverts the signal between input and output is called a what?
common emitter
What is non inverting amplifier?
The amplifier whose output is inphase with it input means if we consider voltage amplification then there is zero phase shift in input and output
Difference between oscillator and amplifier?
The amplifier projects the audio signal into something we can comprehend. The oscillator creates a fixed or variable pitch, which is fed to the amplifier. Amplifiers are circuits which transfer an input signal into an output signal. Oscillators are autonomous circuits powered by a constant energy source. They produce a steady state signal e.g. a sinusoidal signal or a chaotic signal.
What is the function of an attenuator in cro?
An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. attenuator just decrease its amplitude and the attenuator you can take it as a opposite of amplifier. Amplifier just modifies the input signal gives amplified output signal
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?
Answer is GAIN
What is a Scaling amplifier?
3-63A SCALING AMPLIFIER is a special type of summing amplifier with the output signaldetermined by multiplying each input signal by a different factor (determined by the ratio of the input-signal resistor and feedback resistor) and then adding these products
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
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.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
What is gain on guitar amps?
Gain, usually measured in decibels, is the ratio of output to input power. A more sensitive amplifier will have higher gain settings requiring less input signal.
Am amplifier that inverts the signal between input and output is called a what?
common emitter
What effect does an amplifier have on the frequency of the signal?
A; An amplifier will have no effect on the input frequency however its output may not follow the input frequency at the hi end due to the amplifier limitations
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
What is slew rate?
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
