The Clipping Amplifier is the core of the circuit, it is formed by a variable non inverting opamp amplifier with two diodes to perform the clip action and two filters in the feedback loop ( pass-band = low-pass + high-pass) to shape the amount of clipping and the frequency at which i...
the circuit elements, are generally assumed to be linear unless specifically said not to be so. This assumption is reasonable in most cases of circuit analysis. In the practical testing of circuits and devices it is also the case, but obviously there are limits imposed by considerations such as...
When there are multiple signal inputs, choosing the superposition theorem to solve can simplify the analysis and calculation process. The size of the output signal uo can be regarded as the superposition of the output signal obtained by the independent action of u1 and u2. When u1 acts alone,...
