### Is it true that a sine wave is the only signal that does not change shape in a linear circuit?

Is this always true? No. In fact, make that NO. There are many different types of signals: audio, video, telephone, radio, industrial control sensors, radar, wifi, . . . While no single circuit can ...

### Is it true that a sine wave is the only signal that does not change shape in a linear circuit?

If you scale all of the harmonics of any periodic waveform by the same real value, then it is true that the sum of those harmonics would have the same shape as the original. Consequently, scaling the ...

### Is it true that a sine wave is the only signal that does not change shape in a linear circuit?

A single sinewave will not change its shape through a linear circuit. It may change its amplitude, or its phase however, neither of which change the shape. A signal composed of two or more sinewaves ...

### Is it true that a sine wave is the only signal that does not change shape in a linear circuit?

All signals are sums of multiple sine waves at different frequencies, except a sine wave itself which is not a sum of multiple sine waves at different frequencies, however it could be a sum of two ...

### Is it true that a sine wave is the only signal that does not change shape in a linear circuit?

It would be more correct to say, "A sine wave is the only signal that does not change shape as it passes through any linear circuit" Why? Because given some other signal shape, (for example ...

### Can we solve all linear circuits using only KVL and constitutive relations?

For a network containing $b$ branches and $n+1$ nodes, there are $n$ independent KCL equations and $b-n$ KVL equations for a total of $b$. There are also $b$ V-i relationships, which ...

### Can we solve all linear circuits using only KVL and constitutive relations?

I think your first example is incorrect, there are two knowns: The voltage from the supply is $V1 = \text{5 Volts}$ The value of R1 is 1000 Ohms and there are three unknowns: The current through ...
