Manufacturer:SST Description:the rise section of the signal be expressed accurately with respect to the original sound. However, there is inevitable mismatching between the speakers and amplifiers in current audio systems. Solid- state power amplifiers use negative feedback techniques and operate off a fixed voltage supply, but as speakers are a current element, mismatching in the system inevit- ably occurs. In addition, the speaker impedance charac- teristics are strongly influenced by the electrical reac- tance of the voice coil, and the mechanical reactance of the cone assembly. As a result of this, distortion is gener- ated in the rising sections of audio signals, causing phase shift in the reproduced sound. In addition, imped- ance increases in the treble region which reduces the speaker amplitude and reduces the harmonic compo- nent, and as a result there is a tendency to masking of large mid-frequency signal components that follow, and this makes it difficult to reproduce the rising sections of the sound. |
