... To the discerning eye, this can be improved considerably. The problem is that the character at the upper left above has hard edges, and hence high (spatial) frequencies. Those high frequencies result in aliasing distortion when subsampling. To improve the result, we first lowpass filter the characte ...

Valve RF amplifier
A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
