Indirect FM is obtained by modulation of the phase of the carrier i.e., the instantaneous phase of the carrier varies with the amplitude of the modulating signal. Crystal controlled oscillators are used to generate Indirect FM and then the result is passed through a frequency multiplier to convert the
1. Indirect method for generation of FM signals- Generation of wideband FM signal through frequency multiplication. Armstrong’s Indirect Frequency Modulation Generation Method – Продолжительность: 41:28 Easy Class For Me 183 просмотра.
Exercise 8 (Indirect Method of Generating FM Signals). FM and PM are types of angle modulation. In modulation, the message signal changes the amplitude, frequency, or Frequency Modulation (FM) – the process of combining the message signal with the carrier signal that causes
Methods of Generating FM wave. Direct FM: In this method the carrier frequency is directly varied inaccordance with the incoming message signal to produce a frequency modulated signal. Indirect FM: This method was first proposed by Armstrong. Drawbacks of direct method of FM generation
GENERATION OF FREQUENCY MODULATION 100 5-3.1 FM methods 101 5-3.2 Direct methods 101 5-3.3 Stabilized reactance modulator-AFC 108 5-3.4 Indirect The actual method of modulation varies from one system to another. Modulation may be high level or low level. and the system itself
4 Generation of FM (cont’d) B) Indirect method: Armstrong modulator by using frequency-up conversion that involves 2 methods : Heterodyne It can be achieved by converting the frequency deviation of FM signal to the variation of equivalent voltage. The demodulator will produce an output
of generating frequencyModulated signals Direct Method Indirect Method DIRECT FM. DIRECT FM f i f c k f m t ( ) In a direct FM system the instantaneous frequency is directly varied with the Since FM is produced by PM , the later is referred to as indirect FM. The information signal is first
Frequency modulation and phase modulation are the two complementary principal methods of angle modulation; phase For indirect FM modulation, the message signal is integrated to generate a phase-modulated signal. “Frequency Modulation (FM) Tutorial” (PDF). Silicon Laboratories.
Generation of FM Waves, Direct Method, Parametric variation method, varactor diode, reactance modulator, indirect method: armstrong method.Detection of Fm waves : Balanced frequency descriminator, zero crossing detector, phased lock loop, foster seeley discriminator, ratio detector

Usually, “indirect method” for generating FM refers to Armstrong method described by Chukey. The AM with no carrier or DSB-SC (double side-band It is called “indirect” because it does not generate “directly” a frequency modulation, but instead synthesizes it. Sometimes, in direct method using
This section explains the indirect method of the FM generation in detail. There are essentially two basic methods of generating frequency-modulated signals, namely The indirect method is the preferred choice for frequency modulation when the stability of carrier frequency is of major concern.

4. Direct method • In direct FM generation method, the instantaneous frequency of the carrier is changed directly in proportion with the It is a function of various parameters such as temperature, device ageing etc. 8. Indirect method • This method of FM generation is also known as Armstrong
