Analyzing the 13S1, 13S2 and 13S3 Normal Modes

Authors: Herbert Weidner

The use of specialized filtering techniques allows the identification of three eigen­resonances of the earth near 4800 µHz, which are sensitive to the inner core. Careful programming prevents the formation of interfering intermodulation products and lowers the noise level. The accurately measured frequencies differ by about 1.1% from the PREM predictions.
