The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.
One disadvantage of the standard amplitude modulation system is that 67% of the power is used for the carrier, but the carrier transmits no information, so it can be considered as wasted power.The 34% remaining power is split between two mirror opposite sidebands so, in effect, you really only have 17% of your power used to carry the signal.

There is no effect on frequency but the amplitude is increased
No effect on frequency but increases it's amplitude.
The BJT is the bipolar junction transistor, the PCT is the point contact transistor, the UJT is the uni-junction transistor, the SBT is the surface barrier transistor, the FET is the field effect transistor, the GJT is the grown-junction transistor, the AJT is the alloy-junction transistor, and the DFT is the drift field-junction transistor.
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .

Frequency drift of the local oscillator can cause distortion and loss of signal in the demodulated output, while phase drift can lead to phase error which affects the accuracy of demodulation in synchronous detection of DSB-SC modulation. Both drifts can introduce errors and reduce the quality of demodulated signal.
Tremolo is the generic term in musical notation. A trill can be a short tremolo Sometimes this effect is called vibrato, e.g in singing. On electric organs it is sometimes called "Lesley effect" On a guitar tremolo can be made with a "whammy bar". Arpeggio is similar to tremolo on certain instruments. The vibration can either be a frequency modulation or an amplitude modulation (or a combination).
MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
Its a Transistor used in JFET (Junction Field Effect Transistor)
The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."
Frequency has no effect on teh amplitude of a wave.

In the transistor, first letter denotes the material and the second letter denotes about the type of device. Hence here in sk100 transistor, first letter s denotes that it is a silicon transistor and second letter k denotes that it is a hall effect device.So, sk100 is a hall effect silicon transistor....
Frequency does not have a direct effect on the amplitude of a wave. The amplitude of a wave is determined by the energy of the wave, while frequency refers to the number of wave cycles in a given period of time. Changing the frequency of a wave will not alter its amplitude.
Field Effect Transistor A: basically a silicon bar where the conduction is controlled by a field since there is no connection to the gate the impedance is very high
