Block diagram display

Fig. 1 shows the block diagram of the vibrometer, in which the most sensible to small phase variations interferometric scheme is employed. It consists of the microwave and the display units. The display unit consists of the power supply 1, controller 2 of the phase modulator 3, microprocessor unit 9 and low-frequency amplifier 10. The microwave unit contains the electromechanical phase modulator 3, a solid-state microwave oscillator 4, an attenuator 5, a bidirectional coupler 6, a horn antenna 7 and a microwave detector 11. The horn antenna is used for transmitting the microwave and receiving the reflected signal, which is mixed with the reference signal in the bidirectional coupler. In the reference channel the electromechanical phase modulator is used to provide automatic calibration of the instrument. To adjust the antenna beam to the object under test, the microwave unit is placed on the platform which can be shifted in vertical and horizontal planes.

We are now finished with our top level block diagram and can now edit each of the blocks to create the detailed circuit for the block. We will start with BLK1. Click the LEFT mouse button on the block to select it, and then click the RIGHT mouse button on the block to display a menu ... 

The 5 ns pulses of about 10 electrons released at the anode by a photon absorbed by the photocathode of a PM tube can be used to count photons. In such instruments the intensity of light is displayed as a count per second which varies between about 15 (dark count) and 105. A photon-counting detector system is of course much more complex than the simple PM/ampli-fier used in conventional spectrofluorimeters. Figure 7.27(a) is a block diagram of such a photon counter (b) gives a simple illustration of the important process of pulse selection through a discriminator. The output of... 

A block diagram of a scanning-type electron microscope is given in Fig. 5. Major elements of the instrument include the electromagnetic lenses that are used to form the electron probe, the scan coils that sweep the beam over the sample, the detector that collects the secondary electrons, and the amplifying means where the secondary electrons are amplified and fed to the cathode ray tube for display. Since the cathode ray tube is scanned in synchronization with the electron beam, the resulting picture corresponds to the area of the sample being examined. 

Large metabolic charts have been designed to display all the major biochemical pathways. Such charts present a bewildering array of interconnected pathways, making it difficult to appreciate relationships between different pathways. The overall operational aspects of metabolism may be clarified by simpler block diagrams that omit details and focus on functional relationships. Such a functional block diagram for a typical heterotrophic aerobic cell is shown in figure 11.4. The metabolism of such a system is symbolized by two functional blocks ... 

The more recent introduction of commercial STMs incorporating a poten-tiostat and an electrochemical cell has greatly facilitated in situ investigations of electrochemical processes. A block diagram of such STM-electrochemical system is shown in Figure 2.16. Coupled with powerful software, such instruments allow the simultaneous acquisition and display of the electrochemical... 

An optional sieving block is displayed in the schematic diagram of the starch process (Figure 11.9). Depending on the origin of the potatoes, the starch slurry can be contaminated (with wood, sand, peat, etc.) with particles with sizes of 90 pm and larger, and with densities the same as or higher than that of starch. There has been no separation step for this kind of material (for the fraction with diameters <125 pm)...

In a Voigt (or Kelvin) element tlie spring and dashpot are parallel. If a stress is suddenly applied the spring cannot respond immediately because of the resistance caused by the viscous flow (delayed elasticity). Monolayers with a two-dimensional network and viscous material between the cross-links will display such behaviour. So, the increase of the strain is retarded. Eventually the maximum strain / K° is attained, see fig. 3.52a. After cessation of the strain the energy stored in the spring relaxes, again with a rate determined by the parallel viscosity, till AA— 0. Behaviour like this is semi-solid. In the limit of r] - 0 the block diagram of fig. 3.49b is retrieved.
