If you can not reduce the high harmonics from the source, in the face with high harmonics of the signal, we can use filters, filter out a series of high-order harmonic

Not available from source reduced high harmonic in the face of high harmonics of the signal, we can use filter, the filter to a series of high-order harmonic

If is unable from the source to reduce the higher harmonic, facing includes the higher harmonic signal, we may use the filter, filters out a series of higher harmonics

If you are unable to reduce the number of high-level meeting from the source contains high harmonics, in the face of the second harmonic signal, we can be used to filter, a series of high-th harmonic filters

Not available from source reduced high harmonic in the face of high harmonics of the signal, we can use filter, the filter to a series of high-order harmonic
