how does one calculate a gain in signal e.g sine wave. do we take peak-to-peak (or peak) of the output divided by peak-to-peak(or peak) of the input?

Gain in sinusoidal signals refers to the amplification or increase in the amplitude of a sinusoidal signal. It is a measure of how much the signal is amplified from its original strength.
Gain in sinusoidal signals is typically calculated using the ratio of the output amplitude to the input amplitude. It is usually expressed in decibels (dB) and can be calculated using the formula: Gain (dB) = 20 log (Vout/Vin), where Vout is the output voltage and Vin is the input voltage.
There are several factors that can affect gain in sinusoidal signals, such as the properties of the amplifier or circuit used, the frequency of the signal, and external interference or noise. The type and quality of components used in the circuit can also have an impact on the gain.
The gain of a sinusoidal signal can greatly impact its quality. Too much gain can lead to distortion and clipping, while too little gain can result in a weak and distorted signal. Ideally, the gain should be set to the appropriate level to achieve a clear and undistorted sinusoidal signal.
Yes, gain can be negative in sinusoidal signals. This means that the output signal is reduced or attenuated compared to the input signal. Negative gain can be useful in some applications, such as inverting amplifiers or filters, where the output signal needs to be attenuated.
