Digital Instruments in Electronics Measuring:
Automation in Digital Instruments : Automation in Digital Instruments – One of the advantages of digital multimeters is their ease of operation. The reading is easy to take and does not lend itself to …
Decade Counter Circuit : A Decade Counter Circuit is of flip-flops (F/Fs) in cascade, which counts in the base 10 (decimal number system). This means that there is a sequence of ten distinct counts …
Digital Capacitance Meter : Digital Capacitance Meter – Since the capacitance is linearly proportional to the time constant, when a capacitor is charged by a constant current source and discharged through a fixed resistance, …
Digital Frequency Meter : The Principle of Operation of Digital Frequency Meter is given by The signal waveform is converted to trigger pulses and applied continuously to an AND gate, as shown in Fig. 6.4. …
Digital Instruments : Digital instruments are rapidly replacing their analog counterparts. The parameters of interest in a laboratory environment are (i) voltage (ii) current (iii) power (iv) frequency, and (v) logic. We shall consider digital …
Digital Measurement of Time : The Principle of Operation of Digital Measurement of Time is given by The beginning of the time period is the start pulse originating from input 1, and the end of …
Digital Measurements of Frequency Mains : Digital Measurements of Frequency Mains – The conventional method of measuring the frequency of an electrical signal consists of counting the number of cycles of the input electrical …
Digital Multimeter Principles : Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters are simple and inexpensive. Digital …
Digital Phase Meter : The simplest technique to measure the phase difference between two signals employs two flip-flops. The signals to be fed must be of the same frequency. First, …
Electronic Counter : The decade counter can be easily incorporated in a commercial test instrument called an electronic counter. A decade counter, by itself, behaves as a totaliser by totalling the …
IEEE 488 BUS : The purpose of IEEE 488 BUS is to provide digital interfacing between programmable instruments. There are many instrumentation systems in which interactive instruments, under the command of a central controller, …
Microprocessor Based Instruments : Digital instruments are designed around digital logic circuits without memory. The use of microprocessors as an integral part of measuring instruments has given rise to a …
Universal Counter Timer : All measurements of time period and frequency by various circuits can be assembled together to form one complete block, called a Universal Counter Timer. The universal counter uses logic gates which are …
