Chopper Circuit with Input Inductance: The preceding discussion of the chopper assumes ideal conditions and does not consider the effects of inductances in series with the thyristors. With choppers of…
Electronic Communication Articles: This Electronic Communication Articles which includes the following topics: Principles of Communication Systems Need of Modulation in Communication System Bandwidth Requirement in Communication System External Noise in…
Surge Voltage and its Distribution and Control: The design of power apparatus particularly at high voltages is governed by their transient behavior. The transient high voltages or surge voltages originate…
Need of Modulation in Communication System: Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form…
Heat Capacity of Calorimeter: Heat Capacity of Calorimeter - RF power may be directly converted into heat. Water acts as the load, and RF power may be used to heat…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
Primary Standard: Primary Standard - One arrangement is a carefully designed quartz crystal oscillator operating in the range 50 to 100 kHz, having a low temperature coefficient, constant amplitude output…
Pulse Time Modulation(PTM): In Pulse Time Modulation the signal is sampled in the same way as in PAM, but the pulses indicating instantaneous sample amplitudes have a constant amplitude themselves.…
