heterodyne mug
is a signal processing technique invented in 1901 by Canadian inventor-engineer Reginald Fessenden that creates new frequencies by combining or mixing two frequencies. Heterodyning is used to shift one frequency range into another, new one, and is also involved in the processes of modulation and demodulation. The two frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a mixer. In the most common application, two signals at frequencies f1 and f2 are mixed, creating two new signals, one at the sum f1 + f2 of the two frequencies, and the other at the difference f1 − f2. These new frequencies are called heterodynes. Typically only one of the new frequencies is desired, and the other signal is filtered out of the output of the mixer. Heterodynes are the mathematical dual of the phenomenon of "beats" in acoustics. A major application of the heterodyne process is in the superheterodyne radio receiver circuit, which is used in virtually all modern radio receivers.

Very basic mug but does the trick!
The mug is of good quality but advertisement needs to change as the sample photo for ordering gives the customer an illusion that the entire mug is of that color ordered when it is not

What is there to say? It's a mug, with a word in front and the definition in back. Nicely done!
This will be the perfect gift this winter! It even came in a nice little box. The mug seems to be of good quality. It was a bit pricy, got to be honest, but it’ll be very well received.
