A Voltage-Controlled Oscillator (VCO) is a circuit that provides a varying output signal (typically of square-wave or triangular-wave form) whose frequency can be adjusted over a range controlled by a dc voltage. An example of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge

SPSS: Grouped Frequency Distribution FIRST STEP: Under the Transform menu‚ choose Visual Binning… This command assists you in creating a new variable that groups the data. You will then use the new variable to create a grouped frequency distribution. • From the Variables list box‚ click on wt (weight) and then on the arrow to move it to the Variable to Band list box. Click Continue. • Select wt in the left box. Near the top of this dialog box‚ enter a name for your new variable (such

a narrower bandwidth than FM‚ and wider coverage compared with FM radio. The major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference. Also‚ although the radio transmitters can transmit sound waves of frequency up to 15 kHz‚ most receivers are able to reproduce frequencies only up to 5kHz or less. Wideband FM was invented to specifically overcome the interference disadvantage of AM radio. A distinct advantage that FM has over AM is that
