41. Introducing a digital filter requires considerable overhead circuitry, as previously discussed, including two low pass analog filters. 42. Just south of the town is a low pass on the road from Urumchi southeast to Turfan. 43. A scandal over low pass marks for resit exam candidates was quickly redressed by Fitzgerald in October 1997. 44. The transfer function of the Butterworth low pass filter can be expressed in terms of polynomial and poles. 45. Unless the system naturally has sufficient damping, many negative feedback systems have low pass filters or dampers fitted. 46. They are thus easily separated by filtering : highpass for spikes and low pass for the synaptic mechanisms. 47. Once, Frank King threw a low pass to Turner that went off his leg and out of bounds. 48. This gives the L-network the additional feature of harmonic suppression since it is a low pass filter too. 49. Low pass sequencing would allow us at lower cost to march much more rapidly through the human genome,50. This results in a " smoothing " or integration of the output, similar to a low pass filter.
