 | Receiver functions are extracted from the three-component broadband recordings of teleseismic P waveforms at epicentral distances ranging from 30 to 85^o. |
| The SW receiver functions are extracted from a distance range $65$ to $85^o$ and therefore are associated with steep angle of incidences at the base of the crust and low signal strength, generating less strong P to S conversions than closer events. |
| The receiver functions corresponding to Range 1 and 2 show coherent primary and reverberated P to S converted arrivals while the receiver functions corresponding to the most distant events from Range 3 do not generate the same arrivals, possibly due to their steep angle of incidence and low signal strength (Figure 4). |

| By definition, the mixers in the direct down-conversion broadband receiver are driven by an input frequency that is equivalent to the carrier frequency of a selected channel. |
| Thus with a 2-divider approach to the direct down-conversion tuner in a direct-down conversion receiver, both the I and Q components are obtained simultaneously, with a high degree of accuracy. |
| In addition, the new broadband tuner includes a P/P+1 prescaler in which P is maximized without introducing gaps in frequency coverage given a range of potential desired frequencies defined by the channel frequencies, the sub-bands and the various multipliers. |
