The Voltage-Controlled Oscillator The frequency of a VFO can be adjusted by means of a varactor diode in the tuned LC circuit Recall that a varactor, also called a varicap, is a semiconductor diode that works as a variable capacitor when it is reverse-biased The capacitance depends on the reverse-bias voltage The greater this voltage, the lower the value of the capacitance The Hartley and Clapp oscillator circuits lend themselves well to varactor-diode frequency control The varactor is placed in series or parallel with the tuning capacitor, and is isolated for dc by blocking capacitors In Chap 20, we saw an example of how a varactor can be connected in a tuned circuit (Fig 20-9) The resulting oscillator is called a voltage-controlled oscillator (VCO) Varactors are cheaper than variable capacitors or inductors They re also less bulky These are the chief advantages of a VCO over an old-fashioned LC tuned VFO Diode Oscillators At ultrahigh frequencies (UHF) and microwave radio frequencies, certain types of diodes can be used as oscillators You learned about these diodes in Chap 20

Summary

As mentioned above, one of the limitations of TVPs is that they are passed by reference. The TVP is materialized as a temporary table in the tempdb database, and when you pass it to a code module, you are actually passing a reference to that table. SQL Server manages it all for you, so unless you dig (or read the documentation!) you ll never know this. The code samples for this chapter include a TempDB.sql script that lets you explore this behavior, by displaying tempdb s sys.tables and sys.columns catalog views to list the structure of the TVP from within a stored procedure. Nevertheless, despite these limitations, TVPs do a remarkable job in reducing the amount of code that you need to write when you need to pass a set of data to a code module. They are probably among the best of the productivity features that Microsoft introduced in SQL Server 2008.

For example, the following tell block creates a text file named Log Filetxt in the ~/ Desktop/Loading Zone/ folder:
