H211

The H211 is a two-quadrant analog multiplier, a hybrid integrated circuit made in Romania by ICCE (CCSIT-CE) and listed in the Agenda radioelectronistului (2nd edition, 1989) in group 2.1 „Multiplicatoare și divizoare” (multipliers and dividers) of the family „Circuite de calcul analogic și al valorii eficace” (circuits for analog computation and RMS value calculation) [1].

The table describes it as „Multiplicator analogic în două cadrane” [1].

The table gives no parameters or drawing. In it, the first two digits of every code repeat the numbers of its family and group (here 2.1) [1].
