What else can I help you with?
What is collector modulation?
Collector modulation is the amplitude modulation in which modulator varies the collector voltage of a transistor.
What is amplitude modulation derive expression for am wave and modulation index?
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
What is changing amplitude or frequency called?
modulation
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.
Working principle of collector modulator?
A collector modulator is a type of amplitude modulation (AM) used in RF (radio frequency) transmitters, where the modulation of the carrier signal occurs in the collector circuit of a transistor. The input audio signal varies the base current, which in turn controls the collector current and voltage, resulting in variations of the output RF signal's amplitude. This modulation technique allows for efficient transmission of audio signals over radio waves, as the carrier's amplitude reflects the changes in the input signal. The collector modulator is favored for its simplicity and effectiveness in generating modulated signals.
Changing the amplitude or frequency of waves is called?
Modulation.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What is depth of modulation?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
Multiple choice question answer of AM modulation?
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
Amplitude modulation and frequency modulation range in India?
Normal frequency range for amplitude modulation is 550kHz to 1610kHz
