28/03/2011 · In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vi­brating crystal. The crystal (usually quartz) has a high degree of stability in holding con­stant at whatever frequency the crystal is originally cut to operate. The crystal oscillators are, therefore, used whenever great stability is needed, for example, in communication trans­mitters, and ...

Crystals usually operate at fundamental frequencies up to about 15 MHz. Whenever higher frequencies are required a frequency multiplier is placed after the crystal oscillator. The resulting output signal is then a whole multiple of the crystal frequency. Other frequency multipliers often use transistors, which produce harmonics due to their non ...

Radio technology is being used increasingly within everyday life. From broadcast radio and cellular phones to Wi-Fi and other wireless technologies it is widely used. Find out all you need to learn about radio and radio circuits on Electronics Notes.

Crystals have a very high Q-factor and also better temperature stability than tuned circuits, so crystal oscillators have much better frequency stability than LC or RC oscillators. They are used to stabilize the frequency of most radio transmitters, and to generate the clock signal in computers and quartz clocks.

give higher frequency crystals, approximately 0.15 mm at 15 MHz. Crystals are designed and manufac- ... are used to form a tuned LC tank circuit in resonance. The combined ca-pacitive impedance of Cx, Cy and other stray capacitance equals the inductive reactance of the crystal. ... For low frequency circuits, the crystal impedance is relatively ...

The second stage has been tuned to the first odd multiple (3 x). We know that some of our readers will have noticed that the filter used here is a band-rejection (series LC) type. Worse still, when you calculate the rejection frequency you’ll find that it is equal to the fundamental crystal frequency!

Ask your students to brainstorm possible applications for electrical oscillator circuits, and why frequency regulation might be an important feature. ... This circuit is a simple “CW” radio transmitter, used to broadcast information using Morse code. ... while Q values in excess of 10 are considered good for LC tank circuits! Notes:

A spark-gap transmitter is an obsolete type of radio transmitter which generates radio waves by means of an electric spark. Spark-gap transmitters were the first type of radio transmitter, and were the main type used during the wireless telegraphy or "spark" era, the first three decades of radio, from 1887 to the end of World War 1. German physicist Heinrich Hertz built the first experimental ...

The most familiar form of radio receiver is a broadcast receiver, often just called a radio, which receives audio programs intended for public reception transmitted by local radio stations.The sound is reproduced either by a loudspeaker in the radio or an earphone which plugs into a jack on the radio. The radio requires electric power, provided either by batteries inside the radio or a power ...

The frequency multiplier is a class C amplifier with its output circuitry tuned to a harmonic of the input frequency so that the frequency and deviation of the FM carrier are multiplied together. ... (LC) tuned circuits or resistor and capacitor (RC) ... can be calculated by applying the basic parallel LC circuit formula for resonance: fr = 1 ...
