What is the scientific meaning of the phrase 'frequency response'?
Frequency response refers to how a system or device reacts to different frequencies of an input signal. It describes the relationship between the input frequency and the output amplitude or phase of a system, such as an electronic circuit or an audio device. A frequency response plot shows how the system attenuates or amplifies different frequencies.
What is phase discriminator?
A phase discriminator is a circuit or device used to compare the phase difference between two input signals. It is often used in communication systems to demodulate or recover the original signal from a modulated carrier wave by detecting the phase difference between the carrier wave and the modulated signal.
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 is the difference between phase equilibrium and metastability?
Phase equilibrium occurs when two or more phases coexist in a system at equilibrium, with no net change in the phase distribution over time. Metastability refers to the state of a system that is temporarily stable but not in true equilibrium, meaning it can exist in a configuration that is not the most thermodynamically favorable.
Why does an oscilloscope have 2 channels?
An oscilloscope has two channels to allow for simultaneous measurement and comparison of two signals. This is useful for analyzing the relationship between two signals, such as input and output in a circuit, or for measuring phase difference and timing characteristics. Having two channels also enables the oscilloscope to display both signals on the screen for easy visualization and comparison.
What is the phase relationship between the input and output signals of the common collector amplifier?
Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.
Why is it the phase relationship between input and output signals of the common collector amplifier is in phase?
no phase shift
What is phase difference between input and output waveforms of ce amplifier?
180 degree phase shift
Which BJT amplifier has the phase shift between input and output voltage is 180 degree?
The Class A common emitter BJT design has input on the base and output on the collector. This design is inverting, or 180 degrees phase shift.
What is the phase relationship between the input and output voltage of a common emitter amplifier?
In common emitter amplifier circuit, input and output voltage are out of phase. When input voltage is increased then ib is increased, ic also increases so voltage drop across Rc is increased. However, increase in voltage across RC is in opposite sense. So, the phase difference between the input and the output voltages is 180 degrees.
Why output voltage in common base amplifier is in phase to input voltage?
The output of a common emitter stage is inverted, it is not out of phase.
What is an inverting input?
An inverting amplifier is configured such that the output is 1800 out of phase with the input. that is, if a positive input increases the subsequent negative output decreases and vice versa.
What is meant by zero phase frequency?
The zero phase frequency is the frequency at which the phase of the input signal and the output signal match.
Why there is no phase inversion of the input signal at the output signal of the circuit?
Input to output shorted, check active devices, transistors,fet,tubes ect....
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
Waveform is converted to 180 phase in inverting Amplifier?
In an inverting amplifier configuration, the input signal is flipped by 180 degrees relative to the output signal. This is achieved by using a negative feedback configuration with an operational amplifier where the input is connected to the inverting terminal and the output is connected to the feedback loop. As a result, the output waveform is the inverted version of the input waveform.
