Ideally, to meet the low noise, high linearity objectives of a mixer we need some circuit that implements a polarity-switching function in response to the LO input. Thus, the mixer can be reduced to Figure 4.4, which shows the RF signal being split into in-phase (0°) and anti-phase ...
A third resistor branch of the T-structure includes a switch that connects the junction point through the third resistor branch to ground when in a closed state and that turns the third resistor branch into an open circuit when in an open state The switch of the third resistor branch, when...

His variable resistor/capacitor box makes it easy to test out any number of different resistance or capacitance values with a simple turn of a knob. He wired up a pair of pots to provide a wide range of resistance values, being sure to add a low-resistance safety as well as safety overr...
It is also possible to assign an initial value to a variable at the point in the program at which it is declared; this is known as variable initialization. C Program 1.3 gives an example of this with the declared variables resistor1 and resistor2 initialized to 1000.0 and 500.0, respectively...
