A temperature sensor in a production line under normal operating conditions produces a no-load (1.e., sensor current = 0) voltage: v, = Vao COS(mt) R, = 400 2 V = 500 mV w = 6.28 krad/s The temperature is monitored on a display (the load) with a vertical line of light-emitting diodes. Normal conditions are indicated when a string of the bottommost diodes 2 cm in length is on. This requires that a voltage be supplied to the display input terminals where R1 = 12 k2 v, = V, cos(wt) V. = 6 V The signal from the sensor must be amplified. Therefore, a voltage amplifier, shown in Figure P8.2, is connected between the sensor and CRT with R; = 2 k2 R, = 3 k2 Determine the required no-load gain of the amplifier. ER, R. Αι

Question
A temperature sensor in a production line under normal operating conditions produces a no-load (1.e., sensor current = 0) voltage: v, = Vao COS(mt) R, = 400 2 V = 500 mV w = 6.28 krad/s The temperature is monitored on a display (the load) with a vertical line of light-emitting diodes. Normal conditions are indicated when a string of the bottommost diodes 2 cm in length is on. This requires that a voltage be supplied to the display input terminals where R1 = 12 k2 v, = V, cos(wt) V. = 6 V The signal from the sensor must be amplified. Therefore, a voltage amplifier, shown in Figure P8.2, is connected between the sensor and CRT with R; = 2 k2 R, = 3 k2 Determine the required no-load gain of the amplifier. ER, R. Αι
