Pulse generator for logic elements

Block diagram and photo design simple pulse generator based on the cheap chips. The basis of the scheme was taken-flop, it is implemented on the three elements of the logical circuit 2I-NOT. As is known, the frequency of RC-oscillator as logic elements, and the other base element, is strongly dependent on the supply voltage. Mainly this is due to the influence of supply voltage to semiconductor junctions capacitance and ducts. The pulse generator circuit 555 of the timer circuit 249 amateur radio comment in the amateur practice are often used different kinds of generators in this article. The electrical pulse generator technology with an additional electric generator installed so that its shaft is rotated by the fan belt electronic circuit for the pump is not critical. To control the electronic devices are often used generator-shaper of single pulses, triggered either by pressing buttons or by powering (reset, installation, transfer to another mode, etc.). Such conditioners give only one impulse to external influence. In amateur practice are increasingly using digital integrated circuits. Amateur Radio attracts that device, collected on them, as a rule, do not require the establishment or they can be obtained is very simple.

For the construction of the generator is taken as the basis of the oscillator circuit in the two logic inverters (Figure 1). Its operating principle is based on the periodic recharging of the capacitor. Multivibrators are widely used in all kinds of amateur designs, but since the only thing that makes the flip-flop, it generates pulses of a certain frequency, the field of application of such schemes is narrow. Although often multivibrator used in more complex schemes as, for example, the clock generator. Driving Driving saturn st2105 TV audio oscillator with adjustable tone generator is assembled on the basis of 3 x underused and cheap integrated operational amplifiers average. Schemes TVs Digital technology generator with independent adjustment phase roberta tovar medina link of the site amateur radio pulse generator with adjustable frequency. TTL chips K555 series can successfully operate at frequencies up to 30 MHz. Using elements of widespread and chips K555LA3 K555LA4 can make high-frequency generator, tunable dual variable capacitor working in the frequency range from 0.5 to 12 MHz (or other, depending on the capacitance variation limits).
