The HF series circuit is designed as H type. Power amplifier using power tube metal packaging, and power is a large power transformer installation. It has many functions, such as signal overload, intelligent automatic pressure limit, overload automatic attenuation (such as output power, output sh...
The compensation circuit has an input received by parallel amplifiers (V1-Vn) from a video modulator (E). A converter (W1) monitors output power and provides an input, to a regulator (R). The video signal modulated output has a synchronising peak (S), black level (Z) and white value ...
I designed a cascaded High Pass Low Pass/Filter using some tables from my ancient (but still excellent) copy of “RF Circuit Design”, by Chris Bowick. The Octavertl_sdrscript does the calculations for me. A spreadsheet would work well too. ...
