Problem 2 Signal from a pressure transmitter used for monitoring the pressure of steam flowing into a steam turbine in a large power plant is conditioned before digitizing using a low-pass filter, a high-pass filter, and an amplifier. The low-pass filter is set at 20 Hz and the high-pass filter is set at 0.1 Hz. (a) State the range of frequencies passed by the low-pass filter when this filter is used by itself. Indicate units. (b) State the frequency range that is eliminated by the high-pass filter when this filter is used by itself. Indicate units. (c) What is the combination of these two filters called when used for signal conditioning? Problem 3 In Problem 2, state the minimum frequency (Nyquist sampling frequency) with which the signal must be sampled (digitized) for applications.
