Titleblock design in SolidWorks Electrical Drawings (scheme, line diagram, terminal strip, etc.) are created using a copy of the Titleblock file. It is therefore useful to represent all the elements you wish to find in the drawings (logo, graphics, etc.) in the titleblock. The settings (display of the grid, types of lines, styles of texts, etc.) used in the titleblock will automatically be available in the drawing. A titleblock consists of graphics entities (lines, texts, etc.) and attributes allowing the propagation of the data entered in the properties of the elements of the project (book, folder, drawing, etc.). This article will explain how you can use SolidWorks Electrics’s built-in feature “title blocks manager” to customize existing title blocks and make new smart Title Block. Titleblock manager All the titleblocks are stored in a library allowing you to manage existing titleblocks and also to create your own. New: Used to create a new titleblock. Open: Used to open the selected titleblock(s) in the graphical interface in order to modify the SolidWorks Electrical Tips & Tricks graphics and/or the definition of the attributes. DWG import: Used to import a file in AutoCAD format and transform it into a titleblock. Delete: Used to delete the selected titleblock(s). Properties: Used to open the properties of the selected titleblock. Preview: Used to open the selected titleblock in a preview window. Cut / Copy / Paste: Used to duplicate the selected titleblock. List mode / Thumbnails / Configuration: Used to manage the display and display configuration of the titleblocks in the right-hand part of the dialog box. Archive / Unarchive: Used to generate a ZIP file of the selected titleblock(s). Unarchiving allows titleblocks in the archive file to be added to the library. This procedure can be used to exchange titleblocks between two companies for example. Display sub-classes content: Used to activate display of titleblocks stored in the lower levels of the classes. Close the manager when editing titleblock: If this box is checked, the manager closes automatically when you edit a titleblock. Editing a titleblock Whether the titleblock has been imported or created using the Copy/Paste command, you can edit it to make any changes you wish. Select the titleblock you wish to edit in the right- hand part of the titleblocks manager and click on the "Open" icon. The titleblock opens in a graphical interface.

The TDA7000 is a monolithic integrated circuit for mono FM portable radios, where a minimum on peripheral components is important (small dimensions and low costs). The IC has an FLL (Frequency-Locked-Loop) system with an intermediate frequency of 70 kHz. The i.f. selectivity is obtained by active RC filters. The only function which needs alignment is the resonant circuit for the oscillator, thus selecting the reception frequency. Spurious reception is avoided by means of a mute circuit, which also eliminates too noisy input signals. Special precautions are taken to meet the radiation requirements. The TDA7000 includes the following functions: • R.F. input stage • Mixer • Local oscillator • I.F. amplifier/limiter • Phase demodulator • Mute detector • Mute switch QUICK REFERENCE DATA 2,7 to 10 V Supply voltage range (pin 5) VP Supply current at VP = 4,5 V IP typ.

This lab explores superheterodyne single and dual conversion receiver subsystems for analog and digital modulation. Two VHF (30–300 MHz) FM receivers are considered. The ﬁrst receiver employes a wideband (about 200 kHz) IF subsystem centered at 10.7 MHz, while the second employes a narrowband (about 10 kHz) IF subsystem centered at 455 kHz. The narrowband FM receiver also utilizes dual conversion, with the ﬁrst IF at 10.7 MHz and the second IF at 455 kHz. Both receivers have been constructed using readily available radio frequency integrated circuits (RFICs) from NXP semiconductor1 . The receivers are presently in prototype form, constructed on an RF breadboard. In the future the receivers will be fabricated using a custom PCB. The high sensitivity of these receivers allows the wideband receiver to easily tune in FM broadcast stations and the narrowband receiver to receive the Colorado Springs national weather service (NOAA) station, and lab broadcast frequency shift keyed (FSK) digital modulation. Wideband FM Receiver The block diagram for the wideband receiver is given in Figure 1. The low-noise ampliﬁer (LNA) is not implemented at this time, nor is the front-end bandpass ﬁlter (BPF). A short wire (clip lead) will serve as the antenna in the experiment. The receiver requires and external local oscillator... LO frequency is 160 MHz. With low-side tuning for the LO, this means that carrier frequencies up 160 + 10.7 = 170.7 MHz can down-converted. The doubler is a passive circuit from Minicircuits2 , which in simple terms acts as a full-wave rectiﬁer, which has a strong second harmonic component. The mixer output is processed with a multistage IF ampliﬁer, with the 10.7 MHz IF passband shaping formed using ceramic ﬁlters. The nominal bandwidth of each ﬁlter is 280 kHz. Note from the schematic of Figure 2, the ceramic ﬁlters are external to the NXP SA636 RFIC. The ﬁnal stage 10.7 MHz IF BPF SFE10.7 An RF receiver needs to have high gain in order process weak signals arriving from a transmitter located many miles away. High gain over a wide bandwidth is hard to manage from a stability standpoint. Sensitive radio receivers also need to be very selective, that is supply high gain over just a relatively narrow band of frequencies. For the case of an FM receiver the needed bandwidth...
