= 3. A simple shunted dc ammeter, using a basic meter movement with an internal resistance, Rm 1,800 2, and a full-scale deflection current, Irad = 100 μA, is connected into a circuit and gives a reading of 3.5 mA on its 5-mA range. This reading is checked by a recently calibrated dc ammeter which gives a reading of 4.1 mA. The implication is that the first ammeter has a faulty shunt on its 5-mA range. Calculate (a) the actual value of the faulty shunt; (b) the correct shunt for the 5-mA range.

Figure 2 Bit error graph (image insterted)   The numbers on the right of Figure 2 are multipliers. For example, working upwards from the horizontal line representing 10–10, the next horizontal line up represents 2 × 10–10; the next line up represents 4 × 10–10, and so on. The next line up from 8 × 10–10 has no number on the right and represents 10 × 10–10, which is 10–9, as shown on the vertical axis on the left. In mobile cellular communications, the signal-to-noise ratio is often poor, particularly indoors. Suppose that at an indoor location the signal-to-noise ratio is 7 dB. What would the corresponding bit-error probability be?   A rule-of-thumb in mobile communications engineering is that the signal-to-noise ratio indoors is 10 dB worse than outdoors at the same location. Using this rule-of-thumb, what would the bit-error probability be outdoors at the same location as in (a)?   By what factor has the signal-to-noise ratio improved by moving from indoors to outdoors? Express…
