Introduction to Bluetooth Device Testing
To combat narrowband interference and fading in the 2.4GHz ISM band, Bluetooth employs frequency hopping spread spectrum (FHSS). The frequency hops occur at a standard hop rate of 1600 hops/s. The frequency hops follow pseudo-random pattern with uniform probability across all 79 Bluetooth channels (BR/EDR), or optionally

Most thermocouple measurement devices include built-in CJC and automatic scaling in software. If the data acquisition device does not have built-in CJC, the temperature must be measured externally to account for this difference in software.

The voltage gain of the differential amplifier is giving by the ratio 4 3 R R or by 6 5 R R Since the voltage gain should be 1, then R3 = R5 and R4 = R6. This can be easily accomplished by selecting R4 = R6 = 1 kΩ and R3 = R5 = 1 kΩ. U4 is an amplifier with gain of 2.2 according to the problem ...
