How does LC oscillator circuit work?
Oscillators work because they overcome the losses of their feedback resonator circuit either in the form of a capacitor, inductor or both in the same circuit by applying DC energy at the required frequency into this resonator circuit. …
How an LC circuit is being applied to a signal detector?
The resonance effect of the LC circuit has many important applications in communication systems and signal processing. The parallel resonance circuit generates current amplification. The series resonance circuit generates voltage amplification. The LC circuit is used to select or generate a specific frequency signal.
What kind of circuit does a FM transmitter use?
The FM transmitter is a single transistor circuit. In the telecommunication, the frequency modulation (FM) transfers the information by varying the frequency of carrier wave according to the message signal. Generally, the FM transmitter uses VHF radio frequencies of 87.5 to 108.0 MHz to transmit & receive the FM signal.
How is a LC circuit used in a radio?
LC circuits are used for a number of things such as generating signals at the resonant frequency and for picking out a specific frequency (the resonant frequency) from a circuit with many frequencies. Picking out a specific frequency is what’s going on in a crystal radio where the coil and capacitor are connected in parallel.
Why is an oscillator needed in a FM transmitter?
The oscillator is required in FM Transmitter Circuit in order to generate the radio frequency carrier waves. The transmitter circuit is capable of storing the energy for the oscillation as it is a derived from the (inductor and capacitor) LC circuits.
How is the energy stored in a transmitter circuit?
The transmitter circuit is capable of storing the energy for the oscillation as it is a derived from the (inductor and capacitor) LC circuits. The audio I.e input signal obtained from the mic is passed through the base of the transistor in order to modulate the output signal of the LC circuit in FM (I.e frequency modulation wave) Form.
