lm doing an assignment regarding resistance may caused an error in the magnitude of the output voltage.
You have a point: my response was productive, but will it be understood by someone who can't string a sentence together?Averagesupernova said:You can't possibly expect a productive reply based on a post like yours can you?
Nice writeup Nam. The OP's use of the word "balance" confused me, so I waited to try to reply. I couldn't tell if he meant balanced versus unbalanced transmission lines, or matched impedances or whatever. (I didn't even think of the audio multi-channel balance angle...) Hopefully your answer helps him.Nam_Sapper said:You have a point: my response was productive, but will it be understood by someone who can't string a sentence together?
Balance input impedance refers to the resistance that is presented to a balanced input signal. This impedance typically consists of two resistors in series, with one connected to the non-inverting input and the other connected to the inverting input. It is an important factor in maintaining signal integrity and minimizing noise in electronic circuits.
Balance input impedance is important because it helps to ensure that the input signal is accurately represented at the output. A high input impedance allows for a larger range of input signals to be accommodated, while a low input impedance can lead to distortion and signal loss. Additionally, balance input impedance helps to reject common-mode noise, which can improve signal quality.
The balance input impedance of a circuit can affect its performance in several ways. A low input impedance can cause signal distortion and loss, while a high input impedance can lead to noise and instability. Additionally, the balance input impedance of a circuit can impact its frequency response and the amount of power that can be delivered to the load.
The main difference between balance input impedance and single-ended input impedance is that balance input impedance uses two input signals, while single-ended input impedance uses only one. This allows balance input impedance to reject common-mode noise and provide a more accurate representation of the input signal. Single-ended input impedance is more prone to noise and may require additional filtering to achieve the same level of signal integrity.
Balance input impedance is typically measured using a multimeter or an oscilloscope. The input signal is applied to the circuit, and the voltage and current at the input are measured. The input impedance can then be calculated using Ohm's law (Z = V/I). It is important to note that the balance input impedance may vary depending on the frequency of the input signal, so multiple measurements may be necessary for accurate results.
