The bridge rectifier circuit has: Vi = 30 V, RL = 300Ω, diode drop VF = 0.7 V. Find peak output voltage and peak output current.

  • A. 30 V, 100 mA
  • B. 42.42 V, 141.4 mA
  • C. 41 V, 137 mA
  • D. 28.6 V, 95.33 mA

Answer

Step 1: Peak Input Voltage

Vpeak = 30 × √2 = 42.42 V

Step 2: Diode Drop

Drop = 2 × 0.7 = 1.4 V

Step 3: Output Voltage

Vo = 42.42 − 1.4 = 41 V

Step 4: Output Current

Io = 41 / 300 = 0.137 A = 137 mA

Correct Option: C

Coherence Bandwidth and Coherence Time (with MATLAB + Simulator)

🧮 Coherence Bandwidth 🧮 Coherence Time 🧮 MATLAB Code s 📚 Further Reading For Doppler Delay or Multi-path Delay Coherence time T coh ∝ 1 / v max (For slow fading, coherence time T coh is greater than the signaling interval.) Coherence bandwidth W coh ∝ 1 / τ max (For frequency-flat fading, coherence bandwidth W coh is greater than the signaling bandwidth.) Where: T coh = coherence time W coh = coherence bandwidth v max = maximum Doppler frequency (or maximum Doppler shift) τ max = maximum excess delay (maximum time delay spread) Notes: The notation v max −1 and τ max −1 indicate inverse proportionality. Doppler spread refers to the range of frequency shifts caused by relative motion, determining T coh . Delay spread (or multipath delay spread) determines W coh . Frequency-flat fading occurs when W coh is greater than the signaling bandwidth. Coherence Bandwidth Coherence bandwidth is...

ASK, FSK, and PSK (with MATLAB + Online Simulator)

📘 ASK Theory 📘 FSK Theory 📘 PSK Theory 📊 Comparison 🧮 MATLAB Codes 🎮 Simulator ASK or OFF ON Keying ASK is a simple (less complex) Digital Modulation Scheme where we vary the modulation signal's amplitude or voltage by the message signal's amplitude or voltage. We select two levels (two different voltage levels) for transmitting modulated message signals. Example: "+5 Volt" (upper level) and "0 Volt" (lower level). To transmit binary bit "1", the transmitter sends "+5 Volts", and for bit "0", it sends no power. The receiver uses filters to detect whether a binary "1" or "0" was transmitted. Fig 1: Output of ASK, FSK, and PSK modulation using MATLAB for a data stream "1 1 0 0 1 0 1 0" ( Get MATLAB Code ) ...

Antenna Gain-Combining Methods - EGC, MRC, SC, and RMSGC

📘 Overview 🧮 Equal gain combining (EGC) 🧮 Maximum ratio combining (MRC) 🧮 Selective combining (SC) 🧮 Root mean square gain combining (RMSGC) 🧮 Zero-Forcing (ZF) Combining 🧮 MATLAB Code 📚 Further Reading  There are different antenna gain-combining methods. They are as follows. 1. Equal gain combining (EGC) 2. Maximum ratio combining (MRC) 3. Selective combining (SC) 4. Root mean square gain combining (RMSGC) 5. Zero-Forcing (ZF) Combining  1. Equal gain combining method Equal Gain Combining (EGC) is a diversity combining technique in which the receiver aligns the phase of the received signals from multiple antennas (or channels) but gives them equal amplitude weight before summing. This means each received signal is phase-corrected to be coherent with others, but no scaling is applied based on signal strength or channel quality (unlike MRC). Mathematically, for received signa...
