A superregenerative receiver is an AM receiver, so reception of FM signals occurs by tuning the receiver to the most linear part of the selectivity curve; i.e.. slope detection. Of course, the receiver can be tuned to either side of the carrier which can be useful in case of a nearby (in frequency. amplitude 1 Vp-p with frequency deviation constant kHz=V,mod-ulated by sinewave frequency 10 kHz amplitude 1 Vp-p. 2. Explain what is Carson™s rule. 3. What is the di⁄erence between NBFM and wideband FM refer to the Spectral component of the two signals. 4. Use Matlab to draw an FM signal: = 15Hz, carrier amplitude A = V, A m = 1V.
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The frequency of an oscillator is altered "in accordance with the amplitude of a modulating signal". (Dodge & Jerse , p. ) FM synthesis can create both harmonic and inharmonic sounds. Capacitor Microphone FM Generator •Simplest FM Generator (Transmitter) •Refer to Fig (next slide) •LC tank and oscillator generate sine-wave output that goes to antenna •Capacitance on LC Tank is a capacitor microphone (aka condenser mike) •Frequency of impinging sound waves (intelligence) determines the rate of output frequency change •Amplitude of impinging sound waves.
Of course, you cannot apply ordinary amplitude demodulation to a frequency-modulated signal; there is no information encoded in the FM signal’s amplitude. But quadrature (amplitude) demodulation can capture the frequency-encoded information—this is simply the (rather interesting) nature of I/Q signals. By using two amplitude demodulators.

Bax. Here’s a simple FM receiver with minimum components for local FM reception.
Transistor BF (T2), together with a 10k resistor (R1), coil L, 22pF variable capacitor (VC), and internal capacitances of transistor BF (T1), comprises the Colpitts oscillator. The resonance frequency of this oscillator is set by trimmer VC to the frequency of the transmitting station that we wish to listen.
AM/FM Radio Receiver • Design of AM/FM radio receiver • The radio receiver has to be cost effective • Requirements: – Has to work with both AM and FM signals – Tune to and amplify desired radio station – Filter out all other stations – Demodulator has to work with all radio stations regardless of carrier frequencyFile Size: KB.
The following formula, known as Carson’sruleis often used as an estimate of the FM signal bandwidth: BT= 2(∆f +fm) Hz (16) where ∆f is the peak frequency deviation and fmis the maximum baseband message frequency component.
An FM receiver is a superheterodyne type like a typical AM receiver. The functional block diagram of an FM receiver is shown in Fig. The RF section selects the incoming modulated signals and is amplified.
It is then fed into the mixer and local oscillator. Here the frequency of the modulated signal is changed to intermediate frequency. For FM.

Possible selections are: crystal, ceramic and surface acoustic wave filters MW & RF Design / Prof. Wu 30 A key decision in the design of a superheterodyne receiver is the choice of IF frequency.
The IF frequency is. frequency is fixed to around 90 MHz while the receiver is tuned to the desired signaL. The project is to create a FM transmitter-receiver as described above. Theory of FM and operation of circuit are studied before any implementation of hardware. Circuit analysis, testing.
The full audio spectrum ranges form 20 to 20, Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf. AM radio which limits the upper frequency to 5 kHz). Although, some of the signal may be lost above 15 kHz, most people can't hear it anyway, so there is little loss of fidelity.
Figure 2: Frequency spectrum of FM signals with different mf and same modulating frequency. The best way to understand FM signals is to consider a real life example. Let us take an Ann Arbor station, FM, broadcasting at MHz with a power of 50 KW.

The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of the carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of to MHz to transmit & receive the FM signal.
FM demodulator circuits are found in any receiver that uses FM: broadcast receivers, two way radios like walkie talkies and handheld radios that use FM, and any receiver where frequency modulation is used.
FM demodulation basics. In any radio that is designed to receive frequency modulated signals there is some form of FM demodulator or detector. FM Receiver. Construction Superheterodyne FM Frequency Band 88 MHz to MHz Tuning Range 96 MHz to MHz IF Frequency MHz Input Circuit 1.

The power process involves an energy-storing phase and an energy-release phase.In frequency modulation (FM), the frequency of the carrier signal is varied as a function of the message or information.
As with AM, audio content is the most commonly transmitted information using FM, such as in commercial FM broadcast radios operating on channels from 88 to MHz.
