- Help with homework, with the extra portion part too pleasearrow_forwardRedraw the previous circuit and add a 24 V red lamp to indicate the relay coil is on, a 230 V yellow lamp to indicate the solenoid is on, green lamp to indicate the solenoid is off. Use only one relay, which has multiple contacts.arrow_forwardDesign a control circuit so a 24 V relay , start button, and a stop push button (on/off with memory) operates an electromechanical relay to control a 230 V solenoid Next, Redraw the previous circuit and add a 24 V red lamp to indicate the relay coil is on, a 230 V yellow lamp to indicate the solenoid is on, green lamp to indicate the solenoid is off. Use only one relay, which has multiple contacts.arrow_forward
- please answer it handwritten , thanks! will give thumbs uparrow_forwardEXAMPLE 6.3 Suppose the Fourier transform of a pulse is as follows: (1-a) Ть. 2Ть H(f) = < α (To) (-Tof+ 1 +a (1-a) (1+α) ·<|f|≤· 2 2ть 2Ть (1+α) 0, <\f\ 2Ть where 0≤a≤1. Show that this pulse in both time and frequency domains satisfies the Nyquist criterion.arrow_forwardIn matlabarrow_forward

Due to channel noise, errors are made. As shown in Figure 4.4, the channel is assumed to be symmetric, which means the probability of receiving 1 when 0 is transmitted is the same as the probability of receiving 0 when 1 is transmit- ted. The conditional probabilities of error are assumed to be each e. Determine the average prob- ability of error, also known as the bit error rate, as well as the a posteriori probabilities.arrow_forward
- What is the bandwidth requirement in Hz for baseband binary transmission at 64 kbps, if the roll-off factor is 0.25?arrow_forwardEXAMPLE 6.4 Suppose the roll-off factor is 25% and the bandwidth of a baseband transmission system satisfying the Nyquist criterion is 30 kHz. Determine the bit rate. Solution 1+α 1arrow_forwardEXAMPLE 4.9 In a communication system, the noise level is modeled as a Gaussian random variable with m=0 and ² = 0.0001. Determine P(X > 0.01) and P(-0.04 ≤x≤ 0.05). 3arrow_forward
