a) At what time does the peak value of the AC signal occure?
b) What is the frequency,f,of the AC signal?
c) What is the period,T,of the AC signal?
d) At what time does the negitve peak value of the AC signal occur?
An npn BJT has an emitter area of 2micrometer^2. The doping concentration in the base is Nb=3x10^16/cm^3. The BJT is operating with Vt=26mV and ni=1.5x10^10/cm^3. For electrons diffusing thru the base Dn=34cm^2/s.
Assume you have a receiver with an overall noise figure of 23 dB and a bandwidth of 1 MHz. Assuming the minimum acceptable SNR at the output of the receiver is 6 dB, estimate the minimum detectable signal level in dBm at the receiver input.
A waveform generator is connected to an op-amp which has been setup as a voltage follower. The voltage follower is then loaded with a 50 Ohm resistor. What output impedance setting should the waveform generator use
