Web1.Generation of FM from phase modulator: The modulating signal is passed through a low pass RC filter. The filter output is then applied to a phase modulator along with carrier. Hence the extra deviation in the carrier f c due to higher modulating frequency is compensated by reducing the amplitude of the high frequency modulating signals. WebNarrowband FM, NBFM often uses deviation figures of around ±3kHz or possibly slightly more. If quality is not as important for radio communications applications, the much narrower bandwidth has advantages in terms of …

The high-accuracy power meter option provides true RMS measurements using external sensors, including inline sensors.
WebGENERATION OF WIDEBAND FM SIGNALS: The following two methods generate WBFM wave. (1) Direct method (ii) Indirect method Direct Method This method is called as the Direct Method because we are generating a wide band FM wave directly. In this method, Voltage Controlled Oscillator (VCO) is used to generate WBFM.
