The resulting waveform at the output of the mixer will contain, among others, the component whose frequency is equal to the difference between that of the transmitted signal and that of the local oscillator. This signal is used as the input to the IF amplifier. This amplifier is designed so...
a second differencing circuit such as a transconductance amplifier that takes the difference between the two peak signal values, and a combining circuit such as a resistor circuit that additively combines the outputs of the differencing circuits in such a way as to compensate for direct-current offs...
aVery nice to know you and warmly welcome you come to our factory for a visit. We will arrange the car to pick you up from the hotel on 9: 00 am by 9th, July. If you need any other assistance from here, pls always feel free to let me know. 非常好认识您和受欢迎您温暖地来到我们...
An inverted copy of v2 is displayed on the output to show the relationship between the output and the inputs. Conclusion This application note shows that a shunt regulator can be used as a summing amplifier or mixer using the same basic configuration. This demonstrates the flexibility of a ...

Load cell summing box enables the parallel connection of multiple load cells and gives a summated output,widely used for platform scales,batch weighing,vessel weighing system,hopper scales,etc.
difference is less than the predetermined threshold, determining a relative phase difference between the two signals within the crossover region;adjusting a phase of one of the two signals to reduce a phase difference therebetween; andcombining the phase-adjusted signal and the other of the two ...
For one embodiment, threshold circuit500transfers the signal on line505to line500. Accordingly, diode540, amplifier A530, and amplifier A535are used to generate a signal on line505. In particular, A530comprises two inputs and an output. The first input is coupled to R510, R515, and the out...
