Detailed Description

template<class T>
class HIqMultiplier< T >

IQ multiplier (unlinear mixer).

Will mix the input signal with a localoscillator signal thus producing (Tin + Tlo) and (Tin - Tlo)

The localoscillator frequency can be changed by calling SetFrequency(). behaviour while the frequency is transitioning is undefined, if you make large adjustments you may want to reduce the input level while setting the new frequency to avoid clicks or noise (check if it is a problem in your actual case)
