<p>The apparatus comprises a circuit where an input electric signal is connected to a constant pulse duration generator (1), after which there is connected a switch (2) which is connected to a primary current source (3), connected between a supply voltage source (4) and a capacitor (5), and one pole of said capacitor (5) is connected between the switch (2) and the primary current source (3), while after the switch (2) there is connected a main load (6), consisting of a circuit for taking away the constant charge quantity from the capacitor (5) within the ON position of the switch (2). The main load (6) is advantageously connected to the supply voltage source (4), and between the capacitor (5) and the output of the apparatus there is connected a frequency low-pass filter (8). To the output of the apparatus there may be connected an auxiliary constant current load (7), one pole of which being connected either to the capacitor (5) or between the switch (2) and the main load (6). Alternately, to the output of the apparatus, there may be connected the secondary constant current source (9), one pole of which being connected either to the output of the apparatus and to the capacitor (5), or to the switch (2) and to the main load (6).</p> |
