Harmonic Equivalent Circuit of Induction Motor: When fed from an inverter or cycloconverter, the motor terminal voltage is non-sinusoidal but it has half-wave symmetry. A non-sinusoidal waveform can be resolved…
Television Horizontal Deflection Circuit: The function performed by these circuits is exactly the same as already described for the vertical deflection circuits. There are some practical differences. The major one…
TV Receiver Synchronizing Circuits: The task of the TV Receiver Synchronizing Circuits is to process received information, in such a way as to ensure that the vertical and horizontal oscillators…
Characteristics of Data Transmission Circuits: Bandwidth Requirements - Characteristics of Data Transmission Circuits is the most instances consists of pulse-type energy. The data stream is similar to a square-wave signal…
Frequency Multiplier Circuit: A typical Frequency Multiplier Circuit chain is shown in Figure 12-11, The first stage is a transistor crystal oscillator, operating in the VHF region, and this is…
Ratio Detector Circuit: In the Foster-Seeley discriminator, changes in the magnitude of the input signal will give rise to amplitude changes in the resulting output voltage. This makes prior limiting…
