Disadvantages of Continuous Wave Telegraphy Transmitter:
- Higher Signal Power Consumption: Continuous wave (CW) telegraphy transmitters continually emit a signal, regardless of whether there is data to transmit. This results in higher signal power consumption compared to intermittent transmission methods, such as on-off keying (OOK).
- Lower Frequency Efficiency: CW transmitters occupy a constant frequency band, which can lead to interference with other signals in the vicinity. This low frequency efficiency limits the number of simultaneous transmissions in a given area.
- Vulnerability to Jamming: The constant signal emitted by a CW transmitter makes it susceptible to jamming or interference from other sources. This can disrupt communication and make it difficult to receive signals.
- Low Data Rates: CW transmitters typically have lower data rates compared to more advanced modulation techniques, such as frequency shift keying (FSK). This limits the amount of information that can be transmitted within a given period.
- Limited Modulation Options: CW transmitters can only modulate the amplitude or phase of the signal. This limits the range of modulation techniques available for data transmission.
- Complex Transmitter Design: CW transmitters require complex circuitry and components to generate, amplify, and emit the continuous signal. This can increase the size and cost of the transmitter.
- Narrow Bandwidth: The constant signal of a CW transmitter occupies a relatively narrow bandwidth, which can limit the range and reliability of communication.
