FIELD: physics; measurements. ^ SUBSTANCE: present invention pertains to automation and measuring techniques and can be used in analogue-digital signal processing systems. The technical outcome of the invention is shorter sampling time Deltatsampling with simultaneous increase in holding time Deltathold and increase in accuracy of setting the output voltage. The sampling and holding device comprises a non-inverting voltage amplifier (1), control circuit (2), repeater on operational amplifier (3), trigger (4), analogue switch (5), and positive capacitance reactance converter (6). ^ EFFECT: shorter sampling time. ^ 3 cl, 16 dwg |
