Delta Modulation(DM): Delta modulation(DM) is process of modulation in which train of fixed width pulses is transmitted. Their polarity indicates whether the demodulator output should rise or fall at each…
Pulse Width Modulation(PWM): Pulse width modulation of PTM is also often called Pulse Duration Modulation (PDM). In this system, shown in Fig. 18.8, we have a fixed amplitude and starting…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter…
LM335 IC Temperature Sensor: LM335 IC Temperature Sensor - IC sensor produces a voltage or current signal that increases with increase in temperature. It eliminate the linearity errors associated with…
Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle - The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, feedback amplifier. This configuration has a very…
Function Generator Block Diagram: A Function Generator Block Diagram produces different waveforms of adjustable frequency. The common output waveforms are the sine, square, triangular and sawtooth waves. The frequency may…
Trigger Pulse Generator Circuit: The Trigger Pulse Generator Circuit is activated by signals of a variety of shapes and amplitudes, which are converted to trigger pulses of uniform amplitude for…
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…
